As illustrated in Figure P6.3, the periodic square wave is the input signal to an ideal low-pass filter with the frequency spectrum shown. Find the output signal if the input signal has a period of

(a) 40 ms;

(b) 25 ms;

(c) 20 ms;

(d) 12.5 ms;

(e) 10 ms;

(f) 6.25 ms.

Sketch each of the output signals.
