摘要
根据零极点分布对系统频率响应特性的影响规律,设计了一个消除50Hz工频干扰的数字陷波器,并将该陷波器应用于消除心电信号中的50Hz干扰。
Designs a digital trap for eliminating 50Hz power- line interference and applies it in eliminating 5OHz interference on ECG signals, based on the law for the pole - zero distribution to influence on the characteristics of frequency response.
