1)the cross-power-spectral method互功率谱法 2)crosspower spectrum coefficient(CSC)互功率谱比值法 1.In order to avoid these disadvantages,MES was analyzed by crosspower spectrum coefficient(CSC) method.传统检测方法处理表面肌电信号(SMES)时,个体差异比较大,本文针对这一不足,应用互功率谱比值法对肌电信...
Generalized Cross Correlation (GCC) and Cross-power Spectrum Phase (CSP) are commonly used methodologies of TDD calculation. Compared with other conventional methods of applying GCC or CSP alone, the proposed approach combines GCC and CSP to joint estimate LPI without additional hardware, where GCC ...
The Matlab code presented here is an example of Cross-Synthesis – a technique of impressing the spectral envelope of one sound (modulating signal) on the flattened spectrum of another (carrier signal), consisting of the following steps: 1. Short-Time Fourier Transform (STFT) of both the ...
The autospectrum can be written as FFT(u*u) (1)where the star represents the convolution.Recall the with the convolution theorem we found that the fft of the convolution was the product of the fft i.e.FFT(u*u)= fft(u)*fft(u). (2)Thus the power spectra can be obtained in ...

Research on vocal sounding based on spectrum image analysis The improvement of vocal singing technology involves many factors, and it is difficult to achieve the desired effect by human analysis alone. Based on this, this study based on spectrum image analysis uses the... Authors: Jian Sun ...
The power spectrum of interest in the period after the event is given by A whereas that of the preceding baseline period is given by R. ERD or ERS was calculated according to the equation: [Math Processing Error]ERD or ERS=(A−R)/R. Under this definition, ERD was usually expressed ...
Behavioral state-dependent tVNS effects on heart rate variability. (A) Interbeat interval tachogram during passive viewing of Experiment 2. Solid lines show group-average and shaded regions depict ± 1 within-subject SEM34. (B) Group-average power spectrum of the tachogram. Dashed lines de...
