"Windowing and Fourier Transform"

twilmes

Hello everybody. Hopefully a quick question... I'm currently attempting to use the series windowing operator along with the fft operator. My goal is to move through the series, 128 samples at a time, performing an fft on each window. I've setup a process as follows but I think that I may be fundamentally misunderstanding how the windowing operator works since I am getting an error related to nesting the FFT operator inside of the series windowing operator. Do you guys have any suggestions? My desired output would be the spectral data for each windowed chunk of data.

Your help is much appreciated.

Hi twilmes.

The problem with your setting is the parameteroverlapof theWindowing (Series)operator. You should use a value between 0.0 and 1.0.
