Dise o y construcción de un prototipo para la medición de distorsión armónica en redes eléctricas

This investigation work shows the way to implement the rapidly transformed of Fourier using the algorithms of Cooley-Tukey, applied to the analysis and calculation of the harmonic distortion in homes and small businesses that it's don't knows the energy's quality that is delivered daily. The investigation is based on a microcontroller architecture for good perfomance whit a high level language, olso develop the diferent parts of hardware necesary for the reckoning of the FFT of 1024 points and the reckoning of THD level.
