П 3) Consider the system given in Figure 1, with the discrete-time system an ideal LPF with cutoff frequency /8 rad./sec. C/D Discrete-time system D/C x[n] y[n] ↑ T T Figure 1 a. If xc (t) is bandlimited to 5 kHz, what is the maximum value of T that will avoid aliasing in the C/D converter? b. If ¹/7 = 10 kHz, what will the cutoff frequency of the effective continuous-time filter be? c. Repeat Part (b) for ¹/T = 20 kHz.
