Definition of thd in English English dictionary
- Theologiae Doctor (Doctor of Theology)
- Total Harmonic Distortion For a signal, the ratio of the sum of the powers of all harmonic frequencies above the fundamental frequency to the power of the fundamental frequency
- Total Harmonic Distortion the ratio of the fundamental frequency to it's harmonic
- Doctor of Theology
- Total harmonic distortion An audio measurement specification used to determine the accuracy with which a device can reproduce an input signal at its output THD describes the cumulative level of the harmonic overtones that the device being tested adds to an input sine wave THD+n is a specification that includes both harmonic distortion of the sine wave and nonharmonic noise
- Abbreviation for total harmonic distortion
- Total Harmonic Distortion A measure of the distortion content of a signal as represented by equivalent harmonics of that signal and specified as a percentage of the signal amplitude While the equivalent harmonics represented do not actually exist in the signal, their summation would reproduce the distortion component of the signal Further, filter separation of the signal into its fundamental and harmonic frequencies yields the harmonics for identification and measurement comparison with the fundamental
- Total harmonic distortion which is a measure of the sum of all the harmonics produced by an active component due to its nonlinearity expressed as a percentage of the fundamental signal
- Total Harmonic Distortion - The ratio of the total rms signal due to harmonic distor-tion to the overall rms signal, in dB or percent
- An abbreviation for Total Harmonic Distortion
- - 'Total Harmonic Distortion' Audio signals suffer some distortion as they pass through electronic circuits The amount of distortion can be measured expressed as a percentage Power levels should always be referenced to a specific distortion figure The lower the figure the better Look for something like "50W RMS at 0 1% distortion"
- Total Harmonic Distortion
- Total harmonic distortion A measurement of the total of all the harmonics introduced by nonlinear (uneven levels of) distortion in a device This measurement is indicated as a percentage of the strength of the fundamental (lowest level)
- a doctor's degree in theology
- Abbreviation for total harmonic distortion (See Distortion )
- Total Harmonic Distortion A component specification which describes its ability to accurately reproduce a signal Although lower numbers are considered to be better, the human ear typically cannot detect THD ratings below 2% or 3% 3
- The percentage of an audio output signal that consists of spurious harmonic, or multiples of the fundamental frequencies These harmonics are introduced by a power amplifier or other components through which the signal passes; lower figures are better
