An analog signal is band limited to B Hz sampled at Nyquist rate and samples are quantized into 4 levels each with probability

. The information rate is

4 bits/s

B bits/s

4 B bits/s

0.25 B bits/s

Answer: Option

Explanation:

Signal should be sampled at frequency 2B Hz.

Hence, information rate = 2 (2B) = 4B bits/s.
