![]() The first step is performed by the sampler and the second step is performed by the quantizer. Thus, we can define the analog to digital conversion as a two step process. The sampler converts the analog signal to the discrete values and the quantizer represent each level to the fixed discrete finite set of values. It converts an incoming analog signal to the digital signal. The combination of quantizer and sampler in digital communications works as an A/D (Analog to Digital) converter. ![]() ![]() The function of a sampler is to measure the samples of the instantaneous value of the continuous signal and convert it into the discrete values. An analog signal is a continuous time-varying signal, while digital signal is a signal in the discrete form. It is present in almost every type of digital communication system that helps in converting an analog signal to the digital signal. ![]() Sampling is a process performed by a sampler. In digital communication, it is defined as a process of measuring the instantaneous value of an analog signal in the discrete form. Sampling in statistics or research is defined as a method to select a subset from the large data.
