Harmonic frequencies are components of a signal or wave that are multiples of the fundamental frequency. For example a 15 kHz signal will have harmonic frequencies at 30 kHz, 45 kHz, 60 kHz, 75 kHz and so on. These harmonic frequencies reduce in magnitude as they get further and further away from the fundamental frequency of 15 kHz. Harmonic frequencies are best viewed in the frequency domain.
