The harmonic spectrum is the representation of the amplitude of each harmonic order with respect to its frequency.
Figure M9 shows an example of harmonic spectrum for a rectangular signal.
Each type of device causing harmonics draws a particular form of current, with a particular harmonic content. This characteristic can be displayed by using the harmonic spectrum.
