Phase Analysis via Hilbert Transform

This analysis graphs amplitude and phase of a continuous signal in a single trial.

Parameters

Parameter	Description
Reference	Specifies a reference neuron or event.
XMin	Time axis minimum in seconds.
XMax	Time axis maximum in seconds
Ref. Timestamp Number	Reference timestamp number.
Bandpass Filter From (Hz)	Minimum frequency for the bandpass filter.
Bandpass Filter To (Hz)	Maximum frequency for the bandpass filter.
Bandpass Filter Type	The type of the bandpass filter.
FIR Filter Order	The order of the bandpass FIR filter. The order should be 4 or higher. If FIR filter order is odd, order+1 is used.
Send to Matlab	An option to send the matrix of numerical results to Matlab. See also Matlab Options.
Matrix Name	Specifies the name of the results matrix in Matlab workspace.
Matlab command	Specifies a Matlab command that is executed after the numerical results are sent to Matlab.
Send to Excel	An option to send numerical results or summary of numerical results to Excel. See also Excel Options.
Sheet Name	The name of the worksheet in Excel where to copy the numerical results.
TopLeft	Specifies the Excel cell where the results are copied. Should be in the form CR where C is Excel column name, R is the row number. For example, A1 is the top-left cell in the worksheet.

Algorithm

The signal for the specified trial is bandpass filtered and the analytic signal of the result is calculated via Hilbert transform.

The original signal is drawn in light gray, the filtered signal is drawn in dark gray, the amplitude of the filtered signal is drawn in green and the phase is drawn in red.
