The discrete-time system is an ideal low pass filter with frequency response

Consider the system in Figure 4.10. The input signal xc(t) has the Fourier transform shown in Figure P4.20 with Ω0 = 2π(1000) radians/second. The discrete-time system is an ideal low pass filter with frequency response

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

(b) If ωc = π/2, what is the minimum sampling rate such that yr(t) = xc(t)?
