摘要
提出一种对胎儿心动信号做实时处理的方法． 利用快速傅氏变换在频域上直接从多普勒信号中求得胎儿心率． 采用该方案的袖珍式胎儿监护仪具有较强的抗干扰能力， 硬件简单， 适应性强．
This paper presents a real time processing means a digital heart rate cadiotachometer to measure the fetal heart rate directly from the Doppler signals in the frequency domain by means of fast Fourier transformation (FFT). The novel pocket digital fetal heart rate meter is characterized by strong anti interference ability, simple software structure, great adaptability, reliability and rapidity.
