Examples of Digital Signals in Everyday Life
What is a Digital Signal?
A digital signal is a type of signal that represents data as a series of binary digits or “bits” (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.
