Square Waves
A square wave is a type of non-sinusoidal waveform that alternates between two levels, typically high and low, with a sharp transition between them. It is characterized by its rectangular shape, where the signal remains constant for equal durations at both levels. Square waves are commonly used in electronics and signal processing, as they can represent digital signals.
In terms of frequency, square waves have a fundamental frequency and contain odd harmonics, which contribute to their unique sound when used in audio applications. They are often generated by devices like oscillators and are essential in various fields, including telecommunications and music synthesis.
