A transformada de Fourier e o processamento eletrônico dos sinais

Abstract

It is presented in this article a brief history of the scientist Joseph Fourier accompanied by some areas it is applied his famous mathematical technique, called Fourier Transform. As a particular case in order to study and understanding of this technique, is the electronic data processing is approached linked to sound. The process of capturing the data processing for obtaining analog or digital electronic signals by applying Fourier Transform to the data storage is described in sequence. It can thus convert electronic signals and still get a reproduction of the original signal without large losses in sound quality.
