WebThe rectangle wave, also called a pulse wave, may have any number of different duty cycles, but like the square wave, its harmonic spectrum is related to its duty cycle. For example, if a rectangle wave has a duty cycle of 25%, or 1/4, every fourth harmonic is missing. If the duty cycle is 20%, or 1/5, every fifth harmonic would be missing.
