摘要
提出了一种用于当有效信号的频率已知或可求得时的数字滤波方法。讨论了该方法的滤波原理、精度．并给出了计算机模拟滤波程序及其处理结果．通过实验验证．该方法的滤波效果良好．
This paper presents a digit filter method when signal frequency can be known.The principle of this method as well as its precision is analysed.The computer simulation Program of the method is given,and the results calculated are described.
