Question:

Consider the system in figure. The input signal x_c(t) has the Fourier transform shown in figure with ?₀ = 2? (1000) radians/second. The discrete-time system is an ideal lowpass filter with frequency response

(a) What is the minimum sampling rate F_s = 1/T such that no aliasing occurs in sampling the input?

(b) If ?_c = ? / 2, what is the minimum sampling rate such that y_c(t) = x_c(t)?
