Issue Details

I'm trying to use DIAdem's FFT with Two Time Signals function and want to analyze the coherence of two unrelated signals. It should show a coherence close to 0 but I'm always with a coherence equal to 1.

Solution

Select a higher Number of intervals under the tab Time Intervals.

Additional Information

The Number of intervals specifies the number of intervals for the data channel to be analyzed. In other words the amount of "bins" in which the algorithm runs.
