In this work, blood flow data of fetuses ,which have been taken from middle cerebral artery(MCA) by using Doppler ultrasonography, have been analyzed by using fast Fourier transform(FFT), discrete wavelet transform (DWT) and autoregressive model (AR). The principles of modern and classical signal processing methods have been told. The fetal reaction to lullaby ,which has been sung by unknown female individual and mother, has been showed by FFT, DWT and AR model techniques.
