Purpose
Cross phase spectrum
Description
"Cross phase spectrum" computes the frequency dependent phase difference
of two signals x1 and x2, where 
denotes the Fourier transform of x(t).
The type of Fast Fourier Transform (FFT) used can be selected in the Basic Options menu under Fourier.
Warning: Note that if the input signals have different x-axis scales (sampling periods), the signal with the largest scale will be adapted automatically by interpolating between successive sample points. The type of interpolation can be set in the Basic Options menu.
Example
Given two signals, one only being different from the other by a certain (time) delay, one can easily determine the amount of the delay by evaluating the slope of the cross phase of the two signals.
