total harmonic distortion

[′tōd·əl här′män·ik di′stȯr·shən]
(electronics)
Ratio of the power at the fundamental frequency, measured at the output of the transmission system considered, to the power of all harmonics 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; it is expressed in decibels.
