What is analog signal

Signal :

The signal is a physical quantity, which contains some information and which is a function of one or more independent variables.

The signal can be two types :

1. Analog signal

 2.Digital signal

What is an Analoge signal?

An analogue single defined as any continuous signal for which the time-varying feature of the signal is a representation of some other time-varying quantity. 

They can have an infinite number of different values. The Analog signal is classified simple and composite signal. 

An analogue signal is described using amplitude, a period of frequency, and phase. Amplitude mark height of the signal, frequency marks the rate at which the signal is changing and phase marks the position of the wave with respect to time zero.

Let us now discuss some example of the analogue signal.
  1. Temperature
  2. Power
  3. Voltage
  4. Brightness
  5. Sound
  6. Distance
  7. Current
Most of the thing observed in nature are analogue.
