Definition of "Harmonic" |
A frequency that is a multiple of the fundamental frequency. For example, 100 Hz is the second harmonic of 50 Hz, 150 Hz is the third harmonic, and so forth. / A frequency that is a whole-number multiple of a smaller base frequency. Of a sinusoidal wave, an integral multiple of the frequency of the wave. Harmonic percentages of a half sine wave; 2nd, 21.2%, 3rd, 0%, 4th 4.2%, 5th, 0% and 6th harmonic is 1.8%. / A sinusoidal component of the voltage that is a multiple of the fundamental wave frequency. / A harmonic is a signal or wave whose frequency is an integral whole-number multiple of the frequency of some reference signal or wave. The term can also refer to the ratio of the frequency of such a signal or wave to the frequency of the reference signal or wave. / A multiple of the fundamental electrical frequency. Harmonics are present whenever the electrical power waveforms (voltage and current) are not pure sine waves. / Digital Output an output type that will give a digital representation of on or off on 1 or 0 used widely for triggering alarms or relays. / (1) the name associated with a number used to denote the frequency components that exist in a certain fourier series representation for a certain function of time f(t). |
