Examples of Digital Signals in Everyday Life

A digital signal is a type of signal that represents data as a series of binary digits or โ€œbitsโ€ (0s and 1s) for short. In contrast, an analog signal represents data as a continuous wave.

Digital signals are used in many electronic devices, such as computers, smartphones, and televisions, to transmit and process information.

For example, when you send a text message, the message is converted into a digital signal that is transmitted over the internet or cellular network. When you watch a video on a computer, the video is made up of a series of digital signals that are converted into images and sound.
