has a transfer characteristic |H(f) given in the link below. The transmission is at maximum error-free rate of 4,800 bps. Compute the SNR (signal-to-noise-ratio) at the channel output. Does the output signal suffer from any distortion? http://imageshack.us/photo/my-images/263/79465468.jpg/ http://imageshack.us/photo/my-images/263/79465468.jpg/" First.. from the figure given, i know bandwidth, B = 3kHz.. next, R is given.. from channel capacity theorem or Shannon theorem, when the probability of error would approach zero if R < C however, i can't find Channel capacity, C because there is not enough information.. how am i going to solve this question?
