Square Wave

A square wave is a waveform characterised by its abrupt and distinct transitions between two specific voltage levels: high and low. The transitions occur instantly in a square wave, creating a waveform resembling a series of square-shaped pulses. The duration of each high and low state is equal, resulting in a symmetrical waveform. Square waves are commonly used in electronics and signal processing, especially in digital systems, due to their well-defined transitions, making them ideal for representing binary signals. They are employed in applications such as clock signals in digital circuits, pulse-width modulation, and testing signals for various electronic components. The simplicity and clear delineation of voltage levels in a square wave contribute to its utility in digital communication and signal processing.
