摘 要: 介绍了目前设计失真度仪主要采用的几种方法,如基波抑制法、谐波分析法等。通过深入分析这几种常用方法的测量原理,找出了现有失真度测量仪存在的优点和不足。在阐述和分析了模拟数字混合最优滤波(optimization correlative filter, OCF)技术的原理和特点的基础上,提出了基于模拟数字混合最优滤波技术的工频信号失真度测量的新方法。最后,设计了基于模拟数字混合最优滤波技术的工频信号失真度测量系统的硬件电路。
关 键 词: 信号与信息处理;模拟数字混合乘法;最优滤波;失真度

Abstract: This paper introduced two methods of the design of distortion meter, namely fundamental suppression method, harmonic analysis. Through analysis on the measuring principle of these two methods deeply, it found all strengths and weaknesses of them. Based on the principles and characteristics of analog-digital multiplication optimization correlative filter, this paper put forward a new method of frequency signal distortion measurement. Finally measurement system hardware circuit was designed based on analog-digital multiplication OCF.
Key words: signal and information processing; analog-digital multiplication; optimization correlative filter; distortion
