I am a ham radio operator in US. All the books I look at for Software Defined Radio (SDR) assume more knowledge than I have. I am trying to find simplified explanation of how SDR works : how to go from time-series RF samples at antenna to audio output. My ideal book title would be “Elementary DSP : explaining SDR reception and demodulation to 6th grade science class” using verbiage, diagrams, animations, etc rather than math/calculus formulas – maybe have math appendix after descriptions are complete. Demodulation types I am interested in is AM and FM.

I know you probably can’t provide the information I’m seeking, but you might have contacts to pass my request on.

Thank you.
