Design of ECG Signal Acquisition System Based on DSP

AbstractA real-time ECG signal acquisition system with the DSP chip TMS320VC5509A as its core is introduced in this paper. It introduces the design of ECG signal acquisition circuit in detail. ECG signal is analog filtered and amplified and then converted from analog to digital field. Finally, it is displayed in the LCD after digital low-pass filtering in DSP. The collected ECG data can truly reflect the condition of human heart's health. The system has advantages of small volume, little power consumption, low cost and real-time processin
