Naturally Sampled Pulse Amplitude Modulated (PAM) Signal We have already discussed natural sampling. This natural sampling is basically pulse amplitude modulation (PAM). Therefore, it is called naturally sampled PAM signal. Thus, time-domain representation of a naturally-sampled PAM signal will be given as                                                             EQUATION                                         …(3.71) and the frequency-domain representation, i.e. frequency-spectrum of a naturally-sampled… Continue reading »
