Additive components of the square wave with 50%

pulse width

The Pulse Wave

The Pulse Wave is the most versatile wave in a classic

synthesizer because its shape and therefore its harmonic

content can be changed in real time. This is done by

changing the width of the upper and lower portion of

the waveform cycle. These portions are called pulses,

hence the name pulse width. The width of the first pulse

is used to distinguish between different pulse waves and

it is measured in percent. The following picture shows

several pulse waves with different pulse widths:
