FFT Bins

[EPMk]

Hello DasyLab Forum,

I did a complex FFT over two signals and now want to acces a single bin in the spectrum.

What I want to do is to get the phase for one frequency in the signals. Example:

Signal1= cos( 2*pi*t) + cos( 2*pi*5*t);

Signal2= cos(2*pi*5*t+0.3*pi)

and I want to have the 0.3*pi phase for 5 Hz

Thank you very much for your help

Now, I am not an expert in FFT but there is an exampl in DASYLab to measure Phase and I used in succesfully in the past.

You can find in uonder the example worksheets.

Hi thank you for your answer, but i didnt find the example sheet, maybe it isnt present in the german version

I'll post it to you but I can only do it tomorrow morning unless CJ reads this 🙂

Here is the example

Yes that looks like what I was looking for, thank you very much 🙂

Due to the fact that I was using DasyLab10  i couldnt find the example

That example should have been in DASYLab 10... it's missing from DASYLab 12
