一种多用途心电心音信号采集系统的设计
Design of Multi application ECG and PCG Signal Sampling System
【摘要】 本文介绍了一种正交三导联心电和心音信号采集系统。笔记本电脑配以低噪声宽带放大电路、滤波电路和一块PCMCIA式A/D采集卡,组成一套实用的便携式系统。由于采用新型高性能芯片及合理布线,整个系统具有较高的性能。经临床试用,效果良好
【Abstract】 In this paper a new design for orthogonal three channel ECG and PCG signal sampling system was introdued.A notebook computer with a low noise width band amplifier circuit,filter circuit and a PCMCIA A/D sample card,constitutes a pocket practical system.Because of using new integrated circuit chips and reasonable wiring,the system performs a high performance.
