Journal ArticleDOI
Application of higher order statistics techniques to EMG signals to characterize the motor unit action potential
TL;DR: It is observed that the appearance of MUAPs estimated from any EMG (wEMG or sEMG) signal clearly shows evidence of motor unit recruitment and crosstalk, if any, due to activity in neighboring muscles.
Book ChapterDOI
A review of glottal waveform analysis
TL;DR: Glottal inverse filtering is of potential use in a wide range of speech processing applications as the process of voice production is, to a first order approximation, a source-filter process, then obtaining source and filter components provides for a flexible representation of the speech signal for use in processing applications.
Journal ArticleDOI
A New Spike Detection Algorithm for Extracellular Neural Recordings
TL;DR: A new algorithm for spike detection has been developed: this applies a cepstrum of bispectrum (CoB) estimated inverse filter to provide blind equalization to find a sequence of event times or delta sequence.
Proceedings Article
The use of mel-frequency cepstral coefficients in musical instrument identification
TL;DR: This paper examines the use of Mel-frequency Cepstral Coefficients in the classification of musical instruments and concludes that using 4 principal components from the first 15 coefficients gives the most accurate classification results.
Journal ArticleDOI
Characterization of a Flip-Flop Metastability Measurement Method
TL;DR: An equation describing the time interval between data and clock inputs for practical frequencies is developed and it is shown that it takes on discrete values in the absence of jitters and that the presence of jitter perturbs these values.
