- Abstract
Electromyography (EMG) is a diagnostic technique for determining the health status of the muscles and the motor neurons that regulate them. It transmits electrical signals that cause muscles to contract and relax. An EMG translates these signals into graphs or numbers and help the doctors to make diagnosis. The electric signal transmitted by the muscles will have lot of noises. Fast Fourier Transform is one of the most used algorithms for calculating the Discrete Fourier Transform (DFT). It's because of its reduction in computing time and better efficiency. A radix-2 FFT allows to analyze dynamic signals coming through muscle contractions efficiently and same can be precisely implemented using radix-4 Coordinate Rotation Digital Computer (CORDIC) algorithm. Here it deals with the calculation of muscle fatigue using EMG and proposes an ideal FFT core implementation using CORDIC algorithm as a solution for the same.
