TOTAL HARMONIC DISTORTION

Specialty Definition: TOTAL HARMONIC DISTORTION

DomainDefinition

Computing

A)a distortion, due to nonlinear characteristics of a transmission, which results in the presence of harmonic frequencies in the response when a sinusoidal stimulus is applied; b)the ratio of the power of all harmonics as summed measured at the output of the transmission system to the power of the fundamental frequency observed at the output of the system(because of its nonlinearity), when a single frequency signal of specified power is applied to the input of the system.

Specialty Definition: Total harmonic distortion

(From Wikipedia, the free Encyclopedia)

Total harmonic distortion (THD): Of a signal, the ratio of (a) the sum of the powers of all harmonic frequencies above the fundamental frequency to (b) the power of the fundamental frequency.

Note 1: The THD is usually expressed in dB.

Note 2: Measurements for calculating the THD are made at the output of a device under specified conditions.
