## HARMONIC

### Harmonic

A**harmonic**of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency, i.e. if the fundamental frequency is

*f*, the harmonics have frequencies 2

*f*, 3

*f*, 4

*f*, . . . etc. The harmonics have the property that they are all periodic at the fundamental frequency, therefore the sum of harmonics is also periodic at that frequency. Harmonic frequencies are equally spaced by the width of the fundamental frequency and can be found by repeatedly adding that frequency. For example, if the fundamental frequency is 25 Hz, the frequencies of the next harmonics are: 50Â Hz, 75Â Hz, 100Â Hz etc.
