Hi,
I have created a new flash program that shows how windowing is used to reduce leakage in a DFT.
The program also discussed magnitude and power representation of the DFT coefficients.
The program allows you to run a 64 point DFT. The DFT allows two frequency inputs with variable gain on the input levels of each frequency. You can apply six window functions and vary the signals in real time and see how the windowing works on each function.
