If a continuous time signal x(t) with spectrum X(F) is sampled at a rate Fs=1/T samples per second, then what is the scaled spectrum?
A. X(F)
B. Fs.X(F)
C. X(F)/ Fs
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, then what is the scaled spectrum?
A. X(F) B. Fs.X(F) C. X(F)/ Fs 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 of the scaled spectrum Fs.X(F).
