FFT Topic

[RichardD]

Hi Dave - It would be great if you could do a video on FFT.  For example the Agilent scopes you have reviewed have an FFT function built in and there are some general instructions available from Agilent and others about what the FFT function performs.  But there are a lot of questions that aren't explained -- from a "hands on" perspective.  For example, when to use a specific windowing function, why doesn't the fundamental spur start at 0db, usability of scopes like the Agilent MSO 2000/3000 for audio distortion measurements and what limits them, FFT for troubleshooting analog or digital circuits - that sort of stuff that you are so good at explaining!  Cheers, Richard.

Also add an introduction on efficiently implementing it on a DSP and/or FPGA.
