What is difference between baud rate and frequency?

baud rate is the rate of symbol changes...symbol can be of 1 bit, 2 bit , 3 bit etc.... Where as frequency is the inverse of rate of lowest unit in a digital transimission...


What is the difference between baud rate and bit rate?

Both are units of data transmission rates through a communication medium. Baud rate signifies symbol rate. How many symbol changes are transmitted per second. Symbols can contain one bit or more (e.g. 3-bit symbols). Bit is smallest unit in digital transmission or digital communication. Bit has only two states but symbols can have more than 2 states. So symbol may may represent more than one binary bit and so baud rate may or may not be equal to bit rate.

What is the bandwidth of N bit binary coded PCM?

It is same as the bit rate. B = R = nfs where n= no of bits fs= sampling frequency R= bit rate
