Abstract
Often for the study of the energetic systems and equipment's behavior, the Fourier analysis is necessary. This paper presents a way for automatic Fourier analysis with the microcomputer. Two methods are presented: a method called conventional method based on automatic identification of the signal period and a neural network method. The Fourier analysis is made with Fast Fourier Transform. The performances of the proposed methods arc presented.
