Both Bit rate and Baud rate are generally used in data communication,

Bit rate is the transmission of number of bits per second. On the other hand, Baud rate is defined as the number of signal units per second. The formula which relates both bit rate and 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 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 on computer efficiency.While baud rate emphasized on 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 signal.While baud rate is used to decide the requirement of bandwidth for transmission of signal.
