State Channel capacity theorem
Bandwidth and noise power place a restriction upon the rate of information that can be transmitted by a channel. It may be shown that in a channel which is distorted by a white Gaussian noise, one can transmit information at a rate of C bits per second, where C is the channel capacity and expressed as
C = Blog2(1+S/N)
Where, B = channelbandwidth ∈ Hz
S = Signalpower
N = Noisepower
