Both Bit rate and Baud rate are generally used in data communication to measure the speed of data. Bit rate is the transmission of a number of bits per second. On the other hand, the Baud rate is defined as the number of signal units per second. The formula which relates both bit rate and the baud rate is given below:

Bit rate = Baud rate x the number of bit per baud. 

Let’s see the difference between Bit Rate and Baud Rate:

S.NOBit RateBaud Rate
1.Bit rate is defined as the transmission of a number of bits per second.Baud rate is defined as the number of signal units per second.
2.Bit rate is also defined as per second travel number of bits.Baud rate is also defined as per second number of changes in signal.
3.Bit rate emphasized computer efficiency.While the baud rate emphasized data transmission.
4.

The formula of Bit Rate is:

= baud rate x the number of bit per baud 

The formula of Baud Rate is:

= bit rate / the number of bit per baud 
5.Bit rate is not used to decide the requirement of bandwidth for transmission of the signal.While baud rate is used to decide the requirement of bandwidth for transmission of the signal.
6.Bit Rate cannot determine the bandwidth. Baud rate can determine the amount of bandwidth necessary to send the signal.
7.It counts the number of bits traveled per second such as Kbps, Mbps, Gbps, etcIt counts how many times the state of a signal is changing.
