Question:

Consider the system of Figure, with the discrete-time system an ideal lowpass filter with cutoff frequency ?/8 radians/s.?

(a) If x_c(t) is bandlimited to 5 kHz, what is the maximum value of T that will avoid aliasing in the C/D converter?

(b) If 1/T = 10 kHz, what will the cutoff frequency of the effective continuous-time filter be?
