| Abstract(in English) | This paper proposes a method of improving frequency extraction for noise forms based on linear predictive analysis (the conventional method) using an auto correlation and an integral procedure. It is necessary to improve frequency extraction characteristics for mains power frequency to radio frequency from EMC mitigation view points. In this paper, the autocorrelation technique is used to reduce white noise effects on frequency extraction, and the integral procedure aims to emphasize the low frequency spectrum of noise. Our proposed method is introduced and examined by numerical simulations and experiments. The errors between the estimated frequency and a given frequency for simulations are 10-15%. These errors are much small than those for the conventional method. |
