Abstract :
An estimator using an adaptive IIR filter form was used to estimate the frequencies of a biological signal. This signal was the instantaneous ventricular diameter of a dog´s heart. This method was found to be more accurate in determining frequency than traditional FFT and periodogram methods. Its high speed of estimation makes it useful as a real time process.<>
