Web7 mei 2024 · Inter-trial coherence (ITC, also referred to as inter-trial phase-locking factor) is a measure of phase consistency over trials (typically within the range of zero to one). An ITC value close to 0 reflects high variability of phase angles across trials. It is not a connectivity measure, as it does not relate the phase in one channel to that of ... http://math.bu.edu/people/mak/sfn-2013/sfn_tutorial.pdf

Web31 aug. 2024 · Generally, coherence or cross-correlation is used to assess similarity in the time or frequency domain. However, if the two signals being compared are non-stationary, the correlation can change over time. Therefore, the coherence must be represented in a way to show changes across frequency and time. WebThe Fourier magnitude-squared coherence obtained from mscohere (Signal Processing Toolbox) clearly identifies the coherent oscillations at 10 and 75 Hz. In the phase plot of the Fourier cross-spectrum, the vertical red dashed lines mark 10 and 75 Hz while the horizontal line marks an angle of 90 degrees. landscapers ashland https://vindawopproductions.com
