Abstract :
This paper presents an evaluation of autocorrelation techniques for the detection of fetal electrocardiogram signals from abdominal recordings. Raw signals are digitized, then processed and analyzed by a digital computer. The effect of elimination of the maternal signal and of fluctuations in the fetal period is demonstrated. Correlation parameters such as length of signal and sampling rate are investigated.
