Abstract：ECG(electrocardiogram) is an important basis for medical diagnosis of heart diseases.To obtain practical diagnosed information,this paper introduces the ECG filtering algorithms for power-line interference and electromyography noise and implemented by a digital signal processor.By comparing the collected discrete ECG data and ideal ECG signal,we have designed a digital signal processor to eliminate power-line interference and electromyography noise.Then,we get high-quality ECG signal by using MATLAB simulation technology for comparison and analysis.The experiment results prove that the ECG digital filtering algorithms meet the intended design requirements and have the advantages of real-time performance and effectiveness.
