WebAug 26, 2024 · Pulse Amplitude Sampling Pulse amplitude sampling is a basic approach in digital communication. In this method of sampling, the message signal is modulated with a pulse train to acquire a sequence of narrow pulses having a similar amplitude to the continuous-time signal in the pulse. WebMay 31, 2024 · Sampling is defined as, “The process of measuring the instantaneous values of continuous-time signal in a discrete form.”. Sample is a piece of data taken from the whole data which is continuous in the time domain. Ex. When a source generates an analog signal and if that has to be digitized, having 1s and 0s i.e., High or Low, the signal has to …
