If the signal to be analyzed is an analog signal, we would pass it through an anti-aliasing filter with B as the bandwidth of the filtered signal and then the signal is sampled at a rate:
A. Fs≤ 2B
B. Fs≤ B
C. Fs≥ 2B
D. Fs= 2B
Answer:A
If the signal to be analyzed is an analog signal, we would pass it through an anti-aliasing filter with B as the bandwidth of the filtered signal and then the signal is sampled at a rate:
A. Fs≤ 2B B. Fs≤ B C. Fs≥ 2B D. Fs= 2B
Explanation: The filtered signal is sampled at a rate of Fs≥ 2B, where B is the bandwidth of the filtered signal to prevent aliasing.
