Difference between Synchronous and Asynchronous Sequential Circuits

The sequential circuit is one of the major categories of digital logic circuits. Based on the clock input, it is further classified into synchronous circuits and asynchronous circuits. So here this article gives the main comparison between a synchronous and asynchronous sequential circuit to better understand this topic.

Difference between synchronous and  asynchronous sequential circuit:

  • The synchronous sequential circuit is a digital sequential circuit in which the feedback to the input for the next output generation is governed by clock signals, while in the asynchronous sequential circuit are a digital sequential circuit in which the feedback to the input for the next output generation is not governed by the clock signals.
  • In a Synchronous sequential circuit, the memory unit which is being got used for governance is clocked flip flop, on the other hand, unlocked flip flop or time delay is used as a memory element in case of an asynchronous sequential circuit.
  • The states of Synchronous sequential circuits are always predictable and thus reliable, while in the hand there are chances for the asynchronous sequential circuit to enter into a wrong state because of the time difference between the arrival of inputs. This is called race conditions.
  • The synchronous circuit is used in counter, shift register, and memory units, while in the asynchronous sequential circuit are used in low power and high-speed operations such as simple microprocessors, digital signal processing systems, and communication system for an email application, internet access, and networking.
  • Synchronous sequential circuit is easy to design, on the other hand, the presence of feedback among logic gates causes instability issues making the design of asynchronous sequential circuit.
  • Due to the propagation delay of a clock signal in reaching all elements of the circuits the synchronous sequential circuits are slower in its operating speed. While in asynchronous sequential circuits since there are no clock signals, these are fast compared to the synchronous sequential circuits.

Difference Between Synchronous and Asynchronous Counter

As we know that in digital electronics, the counter is a sequential logic circuit consisting of a series of flip flops which is used to count the number of occurrences of input in terms of positive or negative edge transitions. Now based on the way the flip flops are triggered we can differentiate between synchronous and asynchronous counter.

What is the synchronous counter?

The synchronous counter also referred to as a parallel counter contains flip flops that are all in sync with each other. Their clock input is connected together and is triggered by the same external clock signal.

What is the Asynchronous counter?

 An asynchronous counter is the one also referred to as serial counter as here the flip flops that constitute the counter are connected serially and the input clock pulse is provided to the first flip flop in the connection.

Difference between synchronous and asynchronous counter:

  •  Synchronous counter all flip flops are triggered with the same clock simultaneously,  Asynchronous counter, different flip flops are triggered with different clock, not simultaneously.
  • The synchronous counter is faster than the Asynchronous counter in operation, the asynchronous counter is slower than the Synchronous counter in operation.
  • Synchronous counter designing and implementation are complex due to increasing the total number of states,  asynchronous counter designing as well as implementation is very easy.
  • The synchronous counter does not produce any decoding errors, the asynchronous counter produces decoding error.
  • The synchronous counter is also called a parallel counter, the asynchronous counter is also a serial counter.
  • The synchronous counter will operate in any desired count sequence, the asynchronous counter will operate only in a fixed count sequence
  • Synchronous counterexamples are ring counter, johnson counter, asynchronous counter-example counter, there is high propagation delay.




Difference Between Heat and Temperature


As we know that both heat and temperature are the concepts of thermodynamics, that work together to let the energy flow from the hotter body to the cooler body. While the heat depends on the number of particles in an object, the temperature does not depend on a number of particles in an object because it is an average measurement.

Definition of Heat:

As we know, the heat of an object is the aggregate energy of all molecular movement inside the object. A form of energy that is transmitted from one object or source to another due to the difference in their temperature. It moves from a hotter object to the cooler one. Its measurement can be done in energy units, calorie, or joules.

Definition of Temperature:

Temperature is defined as the average kinetic energy of all molecules together, the average energy of all the particles in an object. As an average measurement, the temperature of a substance does not rely on its size and the types. so the temperature is identified how hot or cold an object is, in degrees. It also measures the speed of atoms and molecules of the substance.

Difference between heat and temperature:


  • Heat is nothing but the amount of energy in a body, while in temperature is something that measures the intensity of heat.
  • Heat is one form of energy, it is thermal energy. While in temperature is not an energy, it is the thermal state of a physical body.
  • Heat is represented by Q while in temperature is represented as a T.
  • A calorimeter is a device, which is used to measure the heat. On the other hand, the temperature can be measured by the thermometer.
  • Heat is not a property of the thermodynamic process, while the temperature is a property of the thermodynamic system.
  • Heat value must be in positive form, while in temperature value positive or negative.
  • The main features of heat are that it travels from a hotter region to a cooler region, while in temperature which rises when heated and falls when cooled.
  • Heat measures both kinetic and potential energy contained by molecules in an object, while in temperature measures the average kinetic energy of molecules in a substance.
  • The standard unit of measurement of heat is joules, while that of temperature is Kelvin, but also be measured in Celsius and Fahrenheit.
  • Heat processes of the ability to work, but the temperature is used exclusively to gauge the extent of heat, temperature is the ability to measure the degree of the total amount of heat.
  • Heat is exchangeable, it can flow from one body to another. Temperature is not exchangeable,  only heat can be exchange.
  • Heat is not a fundamental property of matter, while in temperature is a fundamental property of matter.
  • Heat is a path function, Temperature is a point function.
  • The heat flows from the hotter body to the colder body, Temperature increases when heated and decreases when cooled.
  • The heat flow between two bodies does not rely on the amount of heat present in the bodies, while in temperature is decides whether or not heat flow occur between two bodies.

Difference between stationary and progressive waves

Both stationary and progressive wave is the one that allows propagation waves are the two categories in which wave is classified. So here this article gives the main key difference between stationary and progressive waves to better understand this topic.

What is a stationary wave?

A stationary wave or standing wave is static. Which remains in between the boundaries of the medium and does not travel. Each particle within the wave has its characteristic vibrations.

What is a progressive wave?

A progressive wave or traveling wave is the one that allows propagation of energy through the medium as the wave continuously travels in one direction where the amplitude is kept constant.

Difference between stationary and progressive wave

  • The energy is confined within the medium, while the transfer of energy from a location to another within the medium takes place.
  • Each particle of the wave exhibits different vibration at the same instant of time in a stationary wave, while in the progressive wave the transfer of energy from a location to another within. The medium takes place.
  • The molecular vibration of stationary wave in each particle of the wave exhibits different vibration at the same instant of time, while in a progressive wave each particle of the wave possesses similar vibration at the different instant of time.
  • The amplitude characteristics of the particle are different in stationary waves, while in progressive wave amplitude characteristics of particles are the same.
  • The velocity at the mean position of the stationary wave, all particles have their own maximum velocity, while in a progressive wave all particles have similar maximum velocity.
  • The motion is not transferable among the particles, while in a progressive wave motion can be easily transferred among the particles.
  • In double the distance present between 2 consecutive nodes or antinodes, In progressive wave the distance between the point of similar phase at a similar time instant.
  • Change in pressure and density is not uniform in the stationary wave ut the change in pressure and density is uniform in progressive waves. 
  • The crests and through of the waveform appear and disappear at the initial position, while in progressive the crests and throughs of the waveform move in the forward direction.
  • Stationary wave is produced by the intersection of opposite waves, progressive waves are formed by any disturbance in the medium.

Difference Between Open Loop and Closed Loop System

One of the most significant differences in the open-loop and closed-loop control system is that in an open-loop system the desired output does not depend on the control action. Whereas in the closed-loop system the desired output depends on the control action of the system. So here this article gives the main key difference between the open-loop ad close loop system to better understand this topic.

Open-loop control system:

In an open-loop control system, the output does not affect the control action of the system. In other words, the system whose working depends on time is knowns as the open-loop system is free from the feedback. 

Closed-loop control system:

The closed-loop control systems mean the output of the system depends on their input. The system has one or more feedback loop between its output and input. While we are using the closed-loop system design in such a way that they automatically provide the desired output by comparing it with the actual input. The closed-loop system the error signal which is the difference between the input and output.

Difference between open and closed-loop system:

  • The open-loop system which means the output of the system is free from their input. while in the closed-loop system, the desired output depends on their input.
  • The accuracy of the open-loop system is less as compared to the closed-loop system.
  • The open-loop system is not optimized, The closed-loop system is optimized.
  • The open-loop system is called the non-feedback system whereas the closed-loop is the feedback system.
  • The open-loop system gives a fast response, whereas The closed-loop system gives a slow response.
  • The calibration of an open-loop system is difficult as compared to the closed-loop system.
  • The open-loop system the disturbance affected the output, whereas in a closed-loop system the output is not much affected by the disturbances.
  • The open-loop system is not reliable, the closed-loop system is reliable.
  • The open-loop system is stable as compared to closed-loop systems. Here the word stale means the output of the system remains constant even after the disturbances.
  • The construction of systems is easy because few elements are used in the system, The construction of the close loop system is quite difficult. 
  • The output control system has a non-linear response, whereas the input control system has a linear response.
  • The traffic light, automatic washing machine, etc are examples of the output system, whereas the temperature controller, toaster, etc are the example of the closed-loop systems.
  • The control and controlled process are other the two components of the open-loop system. The close loop requires some components like an amplifier, controller, controlled process, feedback system, etc.

Difference Between AC and DC Transmission Line

The most significant difference between the AC and the DC transmission line is that the AC transmission line uses three conductors for power transmission while in the DC transmission line requires two conductors. The other main difference between AC and DC transmission lines is explained in below to better understand this topic.


DC transmission line:

In the DC transmission line, the mercury arc rectifier converts the alternating current into the DC. The DC transmission line transmits bulk power over long distances. At the consumer ends the thyratron converts the DC into the AC.


AC transmission line:

The AC transmission line is used for transmitting the bulk of the power generation end to the consumer end. The power is generated in the generating station. The transmission line transmits the power generation to the consumer end. The power is transmitted from one end to another with the help of step up and step down transformer.

Difference between AC and DC transmission line:


  • The AC transmission line uses three conductors for long power transmission while in DC transmission line uses two conductors for power transmission.
  • The AC transmission lie transmits the alternating current over a long distance. While in DC transmission line is used for transmitting the DC over the long distance.
  • The high voltage drop occurs in the AC terminal line when their end terminals voltage is equal. The DC transmission line is free from inductance and hence no voltage drop occurs across the line.
  • The small conductor is used for AC power transmission as compared to the use of the DC transmission.
  • The dielectric loss occurs in the AC transmission line and not in the DC transmission line.
  • The AC trasmission line less expenasive as comapred to the DC trasmission line.
  • The AC transmission line has the difficulties of synchronization and stability whereas the DC transmission line is free from stability and synchronization.
  • The communication line interference is more in the Ac transmission line as compared to the DC transmission line.
  • At the same voltage, The DC transmission line has less stress as compared to the AC transmission line. Hence DC requires less insulation as compared to AC.
  • The AC transmission line has inductance and surges wheres the DC transmission line is free from inductance and surges. the inductance and the surges are nothing but the wave of the high voltage which occurs for a short duration. 
  • The AC transmission line requires the transformer to step up and step down the voltage, while in the DC transmission line the booster and chopper are used for step up and step down the voltage.
  • The Corona Effect is the phenomenon through which the ionization occurs across the conductor. And this ionization causes the losses in the conductor. The phenomenon of the corona effect occurs only in the AC transmission line and not in the DC transmission line.
  • The phenomenon of the skin effect occurs only in the AC transmission line. The skin effect causes the losses, and this can be reduced by decreasing the cross-section area of the conductor. The phenomenon of the skin effect is completely absent in the DC transmission line.

Difference Between Transmission and Distribution Line

The transmission and distribution line both are used to carry power from one place to the other. difference between transmission and distribution line is explained on the basis of the factors line the basic like usage of the transmission line and distribution line, their working supply phase, voltage, and level of conduction.

Definition of transmission line:

The transmission line is for large distances, their voltage is higher, and they can transport more electricity.

Definition of distribution line:

The distribution line is for short distances, their voltages are lower, and they transport electricity locally.

Difference between transmission and distribution line:


  • The distribution line is thin as compared to the transmission line.
  • The transmission line conducts current at 69 kilovolts or more, but the distribution line conducts current at less than 69 kilovolts.
  • The transmission line carries power or electricity in a three-phase supply system. Distribution systems require a single-phase supply system for carrying electricity.

Difference Between Inverting and Non-Inverting Amplifier

The major difference of operational amplifiers is the inverting and non-inverting amplifiers that the inverting amplifier is the one that produces an amplified output signal which is out of phase to the applied input. While in non-inverting amplifies the input signal level without changing the phase of the signal at the output.


Definition of inverting amplifier:

A type of op-amp that is designed to generate a signal at the output which is 180 degrees out of the phase with the applied input is known as the inverting amplifier. This implies that if the phase of the applied input signal is positive then the amplified signal will be in a negative phase. In a similar way for a signal with a negative phase, the phase of the output will be positive.

Definition of non- inverting amplifier:

An amplifier that produces an amplified signal at the output, having a similar phase as that of the applied input is known as the non-inverting amplifier. This simply means that for an input signal with the positive phase, the output will also be positive.


Difference between Inverting
 and non-inverting amplifier:


  • The gain provided by the inverting amplifier is the ratio of the resistances, while in a gain of the non-inverting amplifier is the summation of 1 ad ratio of the resistance.
  • The input signal in the inverting amplifier is applied at the negative terminal of the op-amp, while in input in case of a non-inverting amplifier is provided at the positive terminals.
  • In the inverting amplifier, the non-inverting terminal is grounded, while in the non-inverting amplifier, the inverting terminal of the op-amp is grounded.
  • The key factor of differentiation between inverting and non-inverting amplifier is done on the basis of the phase relationship existing between input and output. In the case of the non-inverting amplifier, both input and output are in the same phase.
  • The achieved gain of the inverting amplifier is negative thus it provides an inverted output, But the non-inverting amplifier, the gain is positive, and hence the achieved output is non-inverted in nature.
