What is Digital Signal?

Digital signal is a type of signal that represents data as a sequence of discrete values, typically using binary numbers, it also contain different voltage values. Unlike analog signals, which vary continuously over time, digital signals are discrete and quantized, meaning they only take on specific, distinct values.

In digital communication and computing systems, information is encoded into digital signals for transmission, processing, and storage. These signals are commonly used in telecommunications, audio and video processing, computer networks, and many other applications.

Analog and digital signals are two fundamental types of electrical signals used to transmit information in various electronic systems. Analog signals are continuous and vary smoothly over time, while digital signals are discrete and represented by a series of discrete values.

Understanding the difference between these signals is important in telecommunications, electronics, and signal processing. In this article, we will go through the difference between analog and digital signals.
