Dаtum izdаvаnjа: | 1-дец-2005 | Čаsоpis: | Conference Record - IEEE Instrumentation and Measurement Technology Conference | Sažetak: | In this paper, it is shown that the use of random uniform dither in harmonics measurement can significantly shorten the word of applied A/D converter and shorten the word of applied base function (sine and/or cosine), stored in memory, without accuracy loosing. This fact enables design of simple, instrument for harmonics measurement. It is proven theoretically, by simulation and by experiment that 6-bit dithered A/D converter word, 8-bit dithered base function word, and 6×8 (14-bits) multiplier word assure measurement of 16 harmonics (16 sine and 16 cosine components) with 13-bit accuracy. Putting n such simple devices in parallel it is possible to measure n × 16 harmonics simultaneously. The measurement of 1 × 16 harmonics is realized in the small PLD chip. © 2005 IEEE. | URI: | https://open.uns.ac.rs/handle/123456789/12524 | ISBN: | 0780388798 | ISSN: | 10915281 |
