Hi
Analog Devices has some very nice ADC’s that are directly targeted at
doing this general sort of thing. They do not have any “odd” filtering
approach
that creates issues. Some of the early 192 KHz audio parts did not do
very well
past 1/4 the clock rate.
What type of FFT horse power would be needed at 192 Khz ?
not very much..
It's a fairly narrow band signal, It might be more computationally
efficient to do a Bandpass FIR and decimate.
