These can be distinguished as THD F (for "fundamental"), and THD R (for "root mean square"). [12] [13] THD R cannot exceed 100%. At low distortion levels, the difference between the two calculation methods is negligible. For instance, a signal with THD F of 10% has a very similar THD R of 9.95%. However, at higher distortion levels the ...
A total harmonic distortion analyzer calculates the total harmonic content of a sinewave with some distortion, expressed as total harmonic distortion (THD). A typical application is to determine the THD of an amplifier by using a very-low-distortion sinewave input and examining the output.

Total harmonic distortion, or THD is a common measurement of the level of harmonic distortion present in power systems. THD can be related to either current harmonics or voltage harmonics, and it is defined as the ratio of the RMS value of all harmonics to the RMS value of the fundamental component times 100%; the DC component is neglected.

For example, THD is an average of a number of harmonics equally weighted, even though research [citation needed] identifies that lower order harmonics are harder to hear at the same level, compared with higher-order ones. In addition, even-order harmonics are said to be generally harder to hear than odd order.
