Problem 2. (7%) Consider analog pulse amplitude modulation (PAM). The message signal ad- mits the spectral shape that is band-limitd to 20kHz. (a) Determine the Nyquist sampling frequency of m(t). (b) Suppose m(t) is sampled at fo = 48.6 kHz and the pulse shape is rectangular with pulse width T, = 0.8T,, where T, = 1/6. is the sampling period. Determine the bandwidth of the PAM signal s(t). (C) Suppose m(t) is sampled at the minimum frequency such that perfect recovery is possible. Rectangular pulse with duration T, =T, is used. Determine the bandwidth of the PAM signal s(t). (d) State one advantage and one disadvantage of PAM over DSB-SC.
