心音信号采集与分析系统

Heart sound signal gathering and analyzing

主要阐述了心音信号的意义,介绍了传统心音听诊方面的缺点。在此基础上,针对传统心音听诊中的弊端,开发了一种新型的电子心音信号采集、分析和处理系统。这个系统包括高性能的心音传感器、前向处理电路、A/D转换电路和与PC机通信的高速接口电路。心音信号通过心音传感器采集进来,经过前向处理电路进行模拟滤波,由高速接口电路传到上位机。

This paper described a new system for recording, processing and analyzing heart sounds. And this system consisted of high performance sensor gathering heart sounds,the circuit of previously disposing signal,the circuit of A/D converting and the circuit connecting to universal serial bus of personal computer.
