WebMar 8, 2024 · Natural PAM refers to a type of pulse amplitude modulation in which the tops of the pulses follow the shape of the modulating signal. When the modulator is turned on, the pulse train functions as a periodic switching signal, allowing samples of the modulating signal to flow through to the output. WebPulse Amplitude Modulation (PAM) is an analog modulating scheme in which the amplitude of the pulse carrier varies proportional to the instantaneous amplitude of the message signal. The pulse amplitude modulated signal, will follow the amplitude of the original signal, as the signal traces out the path of the whole wave.
