✦ Synopsis

This paper describes a method of performing spectral analysis on Doppler acoustical signals from peripheral blood vessels with the use of an Apple II plus personal computer.

Digitization is accomplished with a commercially available analog-to-digital converter. The data are transformed with a fast Fourier technique, and the resultant information is plotted by an inexpensive X-Y plotter and/or on a television receiver.

Objective: To improve the measurement resolution of the fetal heart rate (FHR) beat-to-beat variation, which is an important prognostic indicator of fetal well-being. Method: The goal was reached using an autoregressive (AR) approach, instead of conventional algorithms based on the Fast Fourier Tran
