Duty cycle of square wave

WebDuty cycles A pulse wave or pulse train is a type of non-sinusoidal waveform that includes square waves (duty cycle of 50%) and similarly periodic but asymmetrical waves (duty cycles other than 50%). It is a term used in synthesizer programming, and is a typical waveform available on many synthesizers. WebWhen looking at the digital square wave output, the duty cycle is the percentage of time that the output is in the high state over the period of the square wave. The image below shows the formula for calculating the duty cycle as well as examples of 50% and 25% duty cycle pulse trains. Phase Angle
