WebIn power systems, harmonics are defined as positive integer multiples of the fundamental frequency. Thus, the third harmonic is the third multiple of the fundamental frequency. Harmonics in power systems are generated by non-linear loads. Semiconductor devices like transistors, IGBTs, MOSFETS, diodes etc are all non-linear loads. WebTotal Harmonic Distortion (THD) characterizes the linearity of an audio device and is a good indication of the distortion present at its output. Assuming you feed the device with a pure tone, THD will represent its deviation from its pure form. The lower the THD, the better! Standard THD tests use a 1kHz sine tone, and so does this page.
