Neoklis,
the best general book on DSP that I have found is by Richard G. Lyons
/Understanding Digital Signal Processing, Third Edition/ (dated 2011).
It's aimed at DSP practitioners, but does include theory. It's
university level, but still practical. It's available in hardback,
paperback and, I think, as an eBook. There are less demanding books, but
few of them include such things as CIC decimator/filters. YMMV, of course.

That's right! In my younger days it was "thermionic valves" (vacuum toobs!)
and germanium transistors, then silicon transistors. And then it was the uA709
Op-Amp and then the 74xx logic gates! It was exciting!
Been there, done that, plus 741 and 748 op. amps. and all sorts of other
stuff. DSP lets us do stuff that would be infeasible, or very expensive,
in the analogue domain.

Yes, I think so too, as a starting point with the best chance of success.
Once I get it to work, if I do, it will be easier to experiment with some
other
arrangements and it might be possible to print out some results to see what
the code does.
The code, of itself, is much less important than the signal processing
chain that it is trying to implement.
Hopefully, that gives you some sort of a route map.
Yes, thanks for the quick and comprehensive reply.
My pleasure.
