本文根据心音频谱图设计了一种新的心功能无损检测仪──心功能频谱仪。此仪器之原理建立在数字信号处理技术及现代频谱分析技术的基础之上，是微机自动检测与诊断技术在医学上的具体应用。
In this paper, we designed a new heart function non-destructive tester-heart function spectrum analyzer based on the heart sound spectrum. The principle of this instrument is based on digital signal processing technology and modern spectrum analysis technology. It is a medical application of microcomputer automatic detection and diagnosis technology.
