Total harmonic distortion (THD) is a popular measure of nonlinearity of a device. Often, it is desired to evaluate this quantity over a sweep of (fundamental) frequency or power, and as such it ...

Total harmonic distortion : The THD of a signal is a measurement of the harmonic distortion present and is defined as the ratio of sum of power of all harmonic components to the power of the ...

Pioneer Electric&Research has introduced a hardened digital multimeter featuring total harmonic distortion measuring on AC voltages. The Model PDM-550 has been designed for flight-line maintenance ...
