What is the highest frequency that is contained in the sampled signal?
A. 2Fs
B. Fs/2
C. Fs
D. None of the mentioned
Answer:A
What is the highest frequency that is contained in the sampled signal?
A. 2Fs B. Fs/2 C. Fs D. None of the mentioned
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.
