	'''[[Harmonics \| Harmonic]]''' : Integer multiples of the fundamental frequency being generated, harmonics are present if a signal is not perfectly sinusoidal or is undergoing intermodulation distortion. Harmonics located outside the desired band for transmission are normally removed with low-pass filters to avoid interference to other radio services.
