The paper discusses digital signal distortion meter with the technology and method of digital signal processing. 本課題研究的數(shù)字化失真度儀採(cǎi)用了數(shù)字信號(hào)処理的技術(shù)和方法。
As the development and application of microcomputer and single-chip microcomputer, the cost of harmonic distortion meter decreases rapidly. 隨著微型計(jì)算機(jī)和單片機(jī)的發(fā)展與應(yīng)用，大大降低了採(cǎi)用諧波分析法的失真度儀的成本。
In this paper, the introduction part introduces detection principle and classification of kinds of distortion meters and introduces the design of digital distortion meter. 論文的緒論部分簡(jiǎn)要介紹了各種失真測(cè)試儀的測(cè)量原理、分類竝給出了數(shù)字式失真度測(cè)試儀的設(shè)計(jì)方案；
