The measurement of the harmonic contents of an electric signal is particularly complex task due to the spectral analysis involved. The present work addresses two basic objectives. The first one is to construct a device capable of carrying out a low error measurement of total harmonic distortion during one cycle of the electric power signal. The second one aims to laying the foundations for embedding the measurement system in an integrated chip.
