Abstract

The current paper describes an application of Pad ́e approximation to obtaina frequency detection method similar to (and, in a sense, more general than) linear predic-tion. While generally not applicable for spectrum estimation, the described method is inmany cases more precise in finding the frequencies of a harmonic signal. A great numberof numerical tests were performed for comparing frequency detection performance of themethod under consideration and of linear prediction. Their methodology and results aresummarized in the article.
