Abstract

Traditional apparatus for Fetal Heart Rate (FHR) measurement is expensive, and also it's harmful to the fetus. Therefore, a portable FHR apparatus using MEMS accelerometer was designed which has the advantage of high safety. A low pass filter was designed and the simulated result from ORCAD shows that this filter is preferable to gain low-frequent FHR signal. Autocorrelation Function (ACF) and spectral analysis were adopted in the FHR signal processing and simulated in MATLAB. The result demonstrates that it can eliminate the noise effectively.
