[A new digital filter method for eliminating 50Hz interference from the ECG].
The article discusses advantages and disadvantages of several conventional digital filter methods. Then, based on Levkov method, the author proposed a new filter method. We use these methods to remove 50 Hz 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 requirement of digital ECG machine.
