Pulse waves are used in many Steve Winwood songs, such as " While You See a Chance". Acoustically, the rectangular wave has been described variously as having a narrow /thin, nasal /buzzy /biting, clear, resonant, rich, round and bright sound. The harmonic spectrum of a pulse wave is determined by the duty cycle. 3% pulse wave, first fifty harmonics (summation in red) Applications

The Fourier series expansion for a rectangular pulse wave with period T is įourier series of a 33.
This is the basis of pulse-width modulation. The average level of a rectangular wave is also given by the duty cycle, therefore by varying the on and off periods and then averaging these said periods, it is possible to represent any value between the two limiting levels. The pulse wave is also known as the rectangular wave, the periodic version of the rectangular function. In many synthesizers, the duty cycle can be modulated ( pulse-width modulation) for a more dynamic timbre. The exact shape of the wave is determined by the duty cycle or pulse width of the oscillator output. It is a term used in synthesizer programming, and is a typical waveform available on many synthesizers. 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%).
