ThdWeight

Returns a real array of 34 elements containing the weighting coeficients from 10Hz to 20kHz. The weighting coeificient vector can be used to calculate the weighted THD of a time-domain vector using a FFT. Note that the

The weighting coefficients are defined in the IEC 61672-1 and IEC 60537 publications. For further information, see the <externalreference href="http:
