Maximum data rate of a channel for a noiseless 3-kHz binary channel is
Answer: C
Correct answer: 6000 bps
By Nyquist's formula for a noiseless channel,
\[ C = 2B\log_{2}V = 2\times 3000\times \log_{2}2 = 6000\ \text{bps} \]
Binary signalling means two levels, so each symbol carries one bit and the rate is twice the bandwidth.
