Frequency and Total Harmonic Distortion Estimation Based on Adaptive Filters
IEEE Latin America Transactions, 2013 In this paper, a low computacional cost total harmonic distortion and frecuency estimation method is proposed. This method is based on adaptive digital filters allowing tracking the fundamental frequency variations. Real time experimental results obtained using a fixed point digital signal processor development kit are presented.

5 mHz highpass filter with −80 dB total harmonic distortions
Electronics Letters, 2012 A fully integrated 5 mHz highpass filter for electrophysiological signal acquisitions is described. Unlike the traditional Gm-C or pseudo-resistor architectures, the proposed continuous-time filter employs the current steering technique, which helps decrease the capacitance area and reduce the total harmonic distortion (THD) simultaneously. This design

Total Harmonic Distortion Factor Evaluation in Shipboard Electrical Networks
Scientific Bulletin of Naval Academy, 2018 Electric propulsion systems for modern civil and military ships, as well as the growing number of electric consumers on board, are a topical issue in terms of onboard electric power quality. In this respect, a growing number of high power static converters are used, which inevitably leads to the appearance, in the electricity distribution network, of ...
