摘要
实现相关滤波的方法很多，本文介绍了一种用简单的数字电路、运算放大器及其它辅助器件构成周期性工作的开关网络代替乘法器，实现相关滤波．其线路简单可靠、经济且精度高。
There are many methods for realizing correlation filtering, the article introduce a switching circuit which is periodic working and composed of simple digital circuit, operational amplifier and other components instead of multiplifier to realize correlation operation. This circuit is simple, economical and its precision is high. And it can realize on_line measurement.
