摘要
讨论几种常用数字滤波方法的优缺点，并在Ｌｅｖｋｏｖ滤波法的基础上，提出一种新的滤波方法。采用上述几种滤波法对５０多人实测的心电信号进行滤波，结果表明，新提出的滤波方法效果最好，可满足数字心电图机实时处理的需要。
The article discusses advantages and disadvantages of several conventienal digital filter methods. Then, based on Levkov method, the author proposed a new filter method. We use these methods to remove 50Hz interference from more than 50 persons' ECG signals. The results show that this new method is the best, and it can satisfy the real time repuirement of digital ECG machine.
