Standards of Distorted Signal for Calibration of Total Harmonic Distortion Meters

摘要

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. This article is based on our previous work directed at the development of a multifunctional THD standard which is now used in the Czech Metrological Institute.
