Hi all,
I'm thinking about coding an application which will need to display a
waterfall much like we see in most digital mode applications.
I'm aware that the basic premise is an FFT but not the finer details
like where windowing functions fit in, how to map the output into
absolute frequencies, etc.
Can anyone suggest a reference, and/or good commented example code?
One option would be to reuse existing code, but I'm actually interested
in writing in Python rather than C.
Thanks
Hamish
