Spectral kurtosis from signal or spectrogram - MATLAB pkurtosis

WebNov 30, 2014 · The Read Biosignal and STFT Spectrogram Toolbox of LabVIEW are used to process the EEG raw data and to produce the EEG Power Spectrum. Then, the pattern of the EEG Power Spectrum are studied to provide the feature vectors for the state machine. The outcome of the study indicates that the movement or direction can be determined based … WebIn an exactly analogous way, measuring a spectrum is an exercise in sampling it at regular intervals in frequency over a limited frequency range. To understand how this comes about we need to consider the whole measurement process. Consider once more the velocity signal from our cylinder wake.
