Sounds suspiciously like some form of quadrature demodulator. Rather
like GEC/Sobel introduced with their 1018 TV chassis in the 1960s.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

Software-Defined Radio. Basically you downmix incoming RF to the audio
range with two mixers fed 90 degrees out of phase. You can then munge
this in various different ways to tune and demodulate various different
radio signals.

quisk, and sat down to code.
Forgive my ignorance, but what is an SDR ?
