The Bit rate is the number of bits (binary zeros and ones) that are transmitted during one second (bits/s). The Baud rate refers to the number of signal units (symbols or characters) that are transmitted per second.
Equation for Baud Rate:
baud rate = bit rate (bits/s) ÷ N, where N is the number of bits represented by each signal shift (symbol or character).For example, if the bit rate is 9,600 bits/s and the communications format require 8 bits per symbol, the baud rate would be 9,600 bits/s divided by 8 bits, which would equal 1200 baud.
Equation for Bit Rate:
Bits/s = baud per second x the number of bits per symbolTherefore, from the above example:
Bits/s = 1200 baud x 8 bits = 9,600 bits/s
