| Abstract: | In this paper,we describe and design a portable heart sound recorder.The program in this paper filters the environmental noise out by the active analog filter and extracts the real-time data of heart sound.By the use of the AD module in the DSPIC chip,we digitize the heart sound and process it.The firmware records the heart sound in FAT32 file system format into a SD card.The software in PC written by LabVIEW traces the heart sound stored in the SD card in the time domain.According to the time domain graph ... |
