harmonic - Computer Definition
A sinusoidal component of a waveform that is an integral multiple of a fundamental frequency. The signal waveform is known as the first harmonic. A waveform that has a component that is twice the frequency of the fundamental frequency, or signal waveform, is known as the second harmonic. An unwanted harmonic causes harmonic distortion. See harmonic distortion.
A multiple of a fundamental frequency occurring at the same time. For example, if the fundamental frequency is 1 kHz, the first harmonic is 1 kHz, the second harmonic is 2 kHz, and so on. Musical instruments oscillate at several frequencies, which are called "overtones." The first overtone is actually the second harmonic, and so on. See harmonic distortion.
