A new style Fourier Demodulator

[tontoko]

If we could eliminate the tank circuit from FM demodulator, we'll make
the size of it much smaller. Here is a conceptual design of FM
demodulator using the successive Fourier transform instead of tank
circuit;

If the size of the tank circuit is significant then the size of the
battery will also be significant. It seems that you propose to use
a DSP instead of a traditional FM detector. Even assuming you
can integrate a DSP, it's voltage regulator any other other peripheral
parts it needs in less space than a LC tank is it going to use
the same or less power?

Definitely the battery needs a considerable space for any portable
devices. Apart from that problem, if that demodulator is embedded in a
chip, it might be expected to mass-produce much easier than ordinal
demodulators because it doesn't have to implement the tank circuit.
