The signal with the amplitude frequency spectrum shown in Figure P6.16 is to be sampled with an ideal sampler.

(a) Sketch the spectrum of the resulting signal for when sampling periods of 40, 50, and 100 ms are used.

(b) Which of the sampling frequencies is acceab1e for use if the signal is to be reconstructed with an ideal low-pass filter?
