www.fpga4fun.com is a cool site.
It's time for me to get back into this. I have an application that requires either a 200K sample rate, or undersampling for a
40K bandwidth. Then I want to apply DSP.
Nobody makes anything to do that at any reasonable price, so it's time to make my own. I remember that there was a generally
available 500K/S ADC a few years back. I see ultra high speed ADC as the next step in SDR, and FPGA makes the logic hardware
much easier to do.
I had something cool going for synchronous AM, DSB and BPSK signal reception a few years back, but it was using a
block-converting FFT. It was still pretty good. Hal has suggested a streaming-serial oriented FFT.
And of course there is the never-ending parade of wierd logic analysis needs...
Also I have to remember to send in my dues again.
