Many times, an estimate for THD is obtained by making what is called a Total Harmonic Distortion plus Noise, or THD+N measurement. THD+N figures are obtained by measuring the total energy present in the output, excluding energy at the input frequency. Usually, this measurement is accomplished by passing the system output through a notch filter, which eliminates energy at …

After calculation, the analyzer divides the total harmonic voltage by the fundamental voltage to get the THD. For example, if the total harmonic RMS amplitude is 0.01 V and the fundamental frequency amplitude is 1 V, then THD is 1%. Picture 7.

To calculate the distortion factor, there are two different formulas: = Distortion att. up to 5% × 100 = THD U= voltage. effective value of all harmonics to the RMS value of all harmonics plus fundamental frequency, that is the total signal. The THD is the ratio of RMS signal of all harmonics to the RMS of the fundamental signal.

The total harmonic distortion (THD) is a measurement of the harmonic distortion present in a signal and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. Distortion factor, a closely related term, is sometimes used as a synonym. In audio systems, lower distortion means the components in a loudspeaker, …
