To make this even worse: You need an analog-digital converter that is
able to digitize the signal in the first place, and those chips are
single-trick ponies (i.e. an ADC tuned for TV signals won't work with
FM radio, even if the output signals you'd need *were* identical,
which they aren't).

Rolling your own is possible but hardly cost-effective, unless you do
this sort of thing as a hobby, of course.

A method of solution is perfect if we can forsee from the start,
and even prove, that following that method we shall attain our aim.
