Standards of distorted signal for calibration of total harmonic distortion meters [PDF]
1998 Conference on Precision Electromagnetic Measurements Digest (Cat. No.98CH36254), 2002 In this article a survey and evaluation of some progressive approaches to the standards of non-linear distortion is reported. Some types of standards of signals with the known total harmonic distortion used for calibration of distortion measuring instruments are proposed.
