What is Emphasis?
With any electrical signals, being the transmission over wires or radio, or the process of converting analog to digital or for whatever purpose, this will require some form of signal conditioning. The reason is that the converting process creates problems either to obtain acceptable signal to noise ratio or signal linearity.
With digital conversion of an analog system the technique is also used to accommodate frequency response as well as dynamic range.
In either case, the conditioning of the incoming signal function must be reversed at the other end, restoring the original signal.
This process is called Emphasis and De Emphasis… Download the PDF of the full article>
