In this article, double threshold, iteration is applied to improve segmentation algorithm based on signal energy, and Short-time Zero-crossing Rate is proposed for the first time to determine the exact boundaries between different components of heart sound. Experimental results indicte that the ...
The performance of the proposed method is compared with three other classic detection methods based on the short-time energy, short-time zero-crossing rate and short-time kurtosis and the obtained results indicate its advantages. The accessibility of the Matlab implementation allows repeatability of ...

Musical Instrument Recognition using Zero Crossing Rate and Short-time Energy Traditionally, musical instrument recognition is mainly based on frequency domain analysis (sinusoidal analysis, cepstral coefficients) and shape analysis to extract a set of various features. Instruments are usually classified ...
The polarization capacitor parameter of electric double layer in the Thevenin battery model is identified by multi-frequency testing. The regularity which the zero-crossing time of polarization capacitor change rate curve is half the time of completely discharge process is got by analyzing the change ...
The time-domain features, such as short-time signal energy, short-time average zero crossing rateand the frequency-domain features, such as spectral centroid and spectral flux features are extracted in this research work. After the feature sequences are extracted, a simple dynamic thresholding ...

Intuitively, the condition on the window transform ensures that all nonzero multiples of the time-domain-frame-rate will be zeroed out over the interval along the frequency axis. When the frame-rate equals the sampling rate ( ), there are no frame-rate multiples in the range . (The range...
