Abstract
The accuracies of four pitch extraction methods are introduced and compared for high-precision perturbation measurement. They include combinations of peak-picking, zero-crossing, and waveform-matching strategies. The effects of sampling frequency, signal-to-noise ratio, pitch frequency, and signal modulation on the accuracies are explored. It is shown that methods with the waveform-matching technique give the best results for most cases. For near-sinusoidal stimuli (e.g., EGG signals), the zero-crossing technique gives higher accuracy than the peak-picking technique. At a low signal-to-noise ratio, a higher sampling frequency does give better results for the waveform-matching technique, but the accuracy of the peak-picking method may reduce as sampling frequency increases. As the signal-to-noise ratio increases, the effect of sampling frequency on accuracy diminishes when interpolation is used. A variety of waveforms are currently being tested to check the suitability of these methods for different applications. [Work supported by NIH.]
