Question

1. In the highest frequency component in an analog signal is 20 KHz, what is the minimum sample frequency

Answer 1

Answer:

What is the highest frequency that is contained in the sampled signal? Explanation: We know that, after passing the signal through anti-aliasing filter, the filtered signal is sampled at a rate of Fs≥ 2B=>B≤ Fs/2. Thus the maximum frequency of the sampled signal is Fs/2.
