Digital Filter for Measuring the Transfer Coefficient Amplitude of the Interference Measures
Georgy Mihov and Dimiter Badarov
The Faculty of Electronic Engineering and Technologies at Technical University of Sofia 8 Kl. Ohridski Blvd Sofia 1000, Bulgaria
Abstract: The interference frequency measures are presented with test procedures. In the interference signal, we have prepared the mean values of the digital filter for measuring the transfer coefficient. We have implemented this system in the MATLAB environment. The power-interference frequency measure is used for the second and third-order harmonics. It also added the elimination of the DC set. We have finally created the amplitude of the interference measures.
