If a continuous time signal x(t) with spectrum X(F) is sampled at a rate Fs=1/T samples per second, the spectrum of the sampled signal is:
A. Non periodic repetition
B. Non periodic non-repetition
C. Periodic repetition
D. None of the mentioned
Answer:A
If a continuous time signal x(t) with spectrum X(F) is sampled at a rate Fs=1/T samples per second, the spectrum of the sampled signal is:
A. Non periodic repetition B. Non periodic non-repetition C. Periodic repetition D. None of the mentioned
Explanation: When a continuous time signal x(t) with spectrum X(F) is sampled at a rate Fs=1/T samples per second, the spectrum of the sampled signal is periodic repetition.
