Why is digital signal better than analog? The values of voltage will be discontinuous. They allow the signals transmitted over a lengthy distance. On the other hand, a digital signal represents a noncontinuous wave that carries information in a binary format and has discrete values. It differs from a digital signal in terms of small fluctuations in the signal which are meaningful. Digital Signal Processing is important because it significantly increases the overall value of hearing protection.

Mainframe computer. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary codei.e., using only the two digits 0 and 1. A digital signal can only take on one value from a finite set of possible values at a given time. The image below is an example of a digitized wave. We can represent digital signals in the form of square waves.
