Surely a web search turned up something?
It sounds like they're using synchronous AM demodulation, and following
the synchronous demodulator (the multiplier) by a low-pass filter that
operates by integrating then decimating.

hi!
i want to demodulate AM signal with DSP...i found an article that says
like this :
demodulator is illustrated as decimation integration filter. It includes a
multiplier portion and an integration/decimation portion.
so can we demodulate AM using decimation method?
and what is decimation integration filter?
thank you...
