Wire data to the signal in input to determine the polymorphic instance to use or manually select the instance. June Part Harmonic distortion analyzer pdf download THD returns harmomic array containing the measured total harmonic distortion for each waveform.
If set to the default value of —1. THD is defined as the ratio of the RMS sum of the harmonics to the amplitude of the fundamental tone.

Warning is TRUE if a warning is generated during processing. For example, for 3rd harmonic analysis, this control should be set to 3 to measure the fundamental, second, and third harmonic. Takes a signal in and performs a full harmonic distortion analyzer pdf download analysis, including measuring the fundamental frequency tone and harmonics, and returning the fundamental frequency, all harmonic amplitude levels, and the total harmonic distortion THD.
Download Help Harmonic distortion analyzer pdf download Only. The multichannel waveform array input should be the result of a multichannel acquisition where each element of the array of waveforms is a distinct and separate channel of data.
01 | Distortion | Root Mean Square
When set to FALSE, this VI continues searching the frequency domain beyond Nyquist by assuming that these higher frequency components have aliased according to harmonic distortion analyzer pdf download following equation. The array index is the harmonic number including 0 DC1 fundamental2 second harmonicThis input provides standard error in functionality.
THD contains the measured total harmonic distortion up to and including the highest harmonic. Harmonic Distortion Analyzer 1 Chan stop search at Nyquist should be set to TRUE default to include only frequencies less than the Nyquist frequency, or half the sampling rate, in the harmonic search.
This output provides standard error out functionality. Harmonic Distortion Analyzer N Chan The multichannel waveform array input should be the aanalyzer of a multichannel acquisition where each element of the array of waveforms is a distinct and separate channel of data.
Harmonic Distortion Analyzer VI
This VI is designed to process a single channel or multiple channels continuously, typically from within a Pef Loop or a While Loop. Use advanced search to set the frequency search range.
All harmonics are measured at integer multiples of this fundamental frequency. To compute THD as a percentage, you must multiply it by
