![]() ![]() FS - this is the sampling rate of the time-series data, in Hertz, e.g.timeSeries - this is the data to be analysed should be a 2-dimensional matrix of size: (number of trials/measurements) x (number of time points).freq - this is a value indicating the frequency to be analysed, in Hertz, e.g.This example shows how to use the cross spectrum to obtain the phase lag between sinusoidal components in a bivariate time series. So far, the beams with the cross phase have been successfully applied in enhancing the self-healing ability of the beam coherence 28, robust far-field imaging 29, flexible auto-focusing of ring Pearcey beams 30, and the dynamics control of optical. The MATLAB code is contained within the following file: PhaseCoherence.m Cross Spectrum and Magnitude-Squared Coherence. Nevertheless, this group preferred to name this structure a special twist phase 27. The code was written using MATLAB 2014b, although uses basic MATLAB functions that are compatible with older and newer versions of MATLAB. This method could be applied to examine patterns in time-series data other than neural data. International journal of audiology, 42(4), 177-219. Using Cross-phase Modulation to Transfer Coherence Between a Cr:Zns Frequency Comb and its Optical Pump Sergey Vasilyev.

We phase-lock a frequency comb based on a few-cycle Cr:ZnS laser oscillator to its narrow-linewidth optical pump, creating a set of mutually coherent optical frequency combs that span from the visible to the long-wave IR. Overview Cross Channel Phasecollects spectra to determine the phase shift and coherence relationships between two sensor locations. The method is described in the following paper: Note that the same method is sometimes referred to as the phase locking value (PLV)-although some implementations of the PLV use a time-series filter rather than conducting the analyses in the frequency domain, as used here. For example, researchers often choose to investigate phase consistency at the frequency of a presented stimulus. The ordinate at the high-coherence frequency corresponds to the phase lag. Plot magnitude-squared coherence function and the phase of the cross spectrum. Rather, it considers their relationship only in terms of the power at a given frequency. This MATLAB function estimates the cross power spectral density (CPSD) of two discrete-time signals, x and y, using Welch’s averaged, modified periodogram method of spectral estimation. This method is often used in electro-encephalography (EEG) analyses to determine the phase consistency of the neural response at a particular frequency, across trials. Relative Phase The coherence does not include any phase information concerning the two processes. The phase coherence value lies between 0 and 1: 1 indicates perfect phase coherence and 0 indicates no phase coherence. The phase coherence value indexes how consistent the phase is across different measurements. This function calculates phase coherence at a frequency of interest, across different measurements. Function to calculate consistency of phase at a given frequency across measurements About the method Some background ![]()
