In electronics, one of the first circuits studied is the rectifier. There are two forms, the half-wave rectifier and the full-wave rectifier. The half-wave rectifier cuts off half of an excitation sinusoid and leaves the other half intact. The full-wave rectifier reverses the polarity of half of the excitation sinusoid and leaves the other half intact. Let the excitation sinusoid be a typical household voltage, 120 Vrms at 60 Hz, and let both types of rectifiers alter the negative half of the sinusoid while leaving the positive half unchanged. Find and graph the magnitudes of the CTFTs of the responses of both types of rectifiers (either form).
