Coherence And Phase Calculation

[Luanna]

Hello!
I have two signals (a RR interval from an ECG signal and its corresponding respiration signal) and i´m trying to calculate coherence and phase for each frequency using the Frequency Response Function.
The coherence is always marking "1" and i´m not using "No averaging".

Could anyone help, please?

Regards,

Luanna

Hi Luana,

I don't know how exactly you are using this function. First of all, I recommend you to consult help about this function and find out how its parameters must be handled. And then, you need to understand how theory about it works. So, I advise you to consult books about this issue. If you have any more question, let me know.
