FREQUENCY-RESPONSE COMPENSATION OF DISTORTING PARTS OF MEASUREMENT SYSTEMS
Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 3
Abstract
In this article a class of digital correction filters is presented. This class of filters has been synthesized in an optimization procedure where two criteria are considered. The first criterion is an approximation of the series interconnection of a distorting system and a compensating filter. The second is the stability of the compensating filter. Their characteristic advantage is full correction of phase distortions independent from the values of established criteria. These filters can be useful for compensation of parts of measurement systems when the discrete transfer function has the zeros on the unit circle or in its proximity. Theoretical results have been verified in numerical simulations.
