Hi, please, somebody tell me: how windowing is practically applied at overall data?
Look to attached image.
In the upper plot there is the plot of ALL SIGNAL SAMPLES.
In the lower plot there are many WINDOW SAMPLES (separated by vertical lines); thus for every sample in window width, we compute SIGNAL SAMPLES .* WINDOW SAMPLES.
Then we JOIN all previous products and get the FULL WINDOWED SIGNAL; on this finally signal we calculate Y = fft(FULL WINDOWED SIGNAL, N fft points)
Is the (although raw) procedure correct?
Thanks, Michele Di Savino
