| Abstract: | 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. |
