List and explain the digitization process?

Digitizing an analog signal is a four-step process

 Anti-aliasing- in this step extreme frequencies of the analog that are unnecessary for its proper sampling are filtered out.
 Sampling process- In the sampling stage the analog signals are selected for building digital values. The higher the sampling rates the more they look like the analog signal. A high sapling rate is preferred over a low one. The sampling rate of a video signal is usually expressed in megahertz(MHz)
 Quantitizing- this means to separate continuously variable signal into defined levels and fitting them into the desired sample range.
 Coding- changes the quantization numbers of each step to binary numbers consisting of 0’s and 1’s and the various grouping of bits
