Fast Fourier Transform Adjusted into 8 Bit Format for Instrumentation Purposes

Abstract

The present article shows an application of Fourier analysis for signal processing. The main characteristic of the project is that the iterative fast Fourier transform radix-2 decimation-in-frequency algorithm had to be adjusted into an 8 bit format for increasing processing speed. The adjusted algorithm was introduce into a microcontroller and used to determine the effort made in a muscle through the acquisition and processing of a microelectric signal.
