基于FPGA的心音信号采集
Heart sound signal collection based on FPGA
摘要
Abstract
This paper introduces a type of heart sound collection system based on FPGA. The system consists of high performance sensor sampling heart sounds, the preproeessing circuit, the A/D conversion module and serial communication circuit. Sensors transfer heart sound signal into electrical signal, which is amplified and filtrated through the pretreatment circuit, and then sent to the FPGA after MD conversion circuit. FPGA will transfer the collected data to PC. The experiment results show that the system can collect heat sounds signal noninvasively, fast and cheaply.关键词
