I understand the purpose of windowing and overlapping windows for FFT calculation and I am trying to visualize it using Dasylab.

I am purposely choosing sample rate, block size and frequency for the generated sine wave so, that the signal is not periodic in one block length and windowing becomes necessary to read the correct frequency and amplitude from the FFT calculation.

My problem is that I am not able to get any change in the windowed signal nor in the FFT results by changing the overlapping parameter. For some reason (and I might be the reason why...) the overlapping does not work.

There is only very limited help or manual content for Dasylab, so I would be thankful if someone has an idea on this forum!

Hello,

I understand the purpose of windowing and overlapping windows for FFT calculation and I am trying to visualize it using Dasylab.

I am purposely choosing sample rate, block size and frequency for the generated sine wave so, that the signal is not periodic in one block length and windowing becomes necessary to read the correct frequency and amplitude from the FFT calculation.

My problem is that I am not able to get any change in the windowed signal nor in the FFT results by changing the overlapping parameter. For some reason (and I might be the reason why...) the overlapping does not work.

There is only very limited help or manual content for Dasylab, so I would be thankful if someone has an idea on this forum!

Thank you!

Vince
