Difference Between Bit Rate and Baud Rate

Bit rate and baud rate both the terms are used in the same way to examine the speed of data, but the bit rate is used when we want to know the number of bits transmitted per unit of time whereas the baud rate is used when we want to know the number of signal unit transmitted per unit of time. Here this article gives information about the main key difference between bit rate and baud rate to better understand this topic.


Definition of bit rate:


The bit rate can be defined as the number of bit intervals per second, Bit interval is referred to as the time needed to transfer one signal bit. It is similar in bit per second, for example, kilobits per second, megabits per second, gigabits per second, etc.

Definition of baud rate:


Baud rate is expressed in the number of times signal can change on transmission line per second, usually, the transmission line uses only two signal states, and make that the baud rate equal to the number of bits per second that can be transferred for the signal.

The main key difference between bit rate and baud rate:

  • Bit rate is also defined as per second travel number of bits, the baud rate is also defined as changes in the signal.
  • Bit rate emphasized on computer efficiency, while the baud rate emphasized on data transmission.
  • Bit rate is defined as the transmission of the number of bits per second, while the baud rate is defined as the number of signal units per second.
  • The formula of bit rate is = baud rate* the number of bit per baud, while the formula of baud rate is bit rate/ number of bit per second.
  • Bit rate is not used to decide the requirement of bandwidth for transmission of signal, while the baud rate is used to decide the requirement of bandwidth for transmission of the signal.
