CARDONA, Duvan; LOPEZ, Danilo  e  HERNANDEZ, Cesar A. Designing and building a harmonic-distorsion measurement prototype for electrical networks. Tecnura [online]. 2013, vol.17, n.35, pp.107-115. ISSN 0123-921X.

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 diferent parts of hardware necesary for the recmicrocontroller architecture for good perfoman-koning of the FFT of 1024 points and the reckoce whit a high level language, olso develop the ning of THD level.

Palavras-chave : algorithm; decimated; twist factor; FFT; THD.
