Distortion Factor

ratio of the r.m.s. value of the harmonic content to the r.m.s. value of the fundamental term

Note 1: The harmonic content is obtained e.g. by subtracting from a non-sinusoidal alternating quantity its fundamental term.

Note 2: The distortion factor is usually expressed as a percentage. It is equivalent to THD, total harmonic distortion
