| Abstract: | ECG signals are weak signals with low frequency, and the measure environment is very complicated so that it is unavoidable that several kinds of interference will be introduced. So the acquiring system must have the feature of high anti-jamming. This paper presents a system for acquiring and processing ECG signals based on P89LPC932 in detail, and offers a circuit for acquiring and conditioning ECG signals, and it also presents the application of wavelet transform in processing ECG signals. The application has indicated the system is simple in hardware, high accurate, and has a low cost. |
