Good morning!
I wish to know what could be the simplest ways of carrying out amplitude demodulation (not for RF), using any integrated solutions that TI might have. The frequency range is maximum around 30kHz. I have come across a few simple analog circuits like envelope detector, multiplier etc. but if there are better and more accurate ways of achieving amplitude demodulation using any IC (like Analog device's AD630) it would make the task much easier.
Best regards,
A
Hi A,
synchronous detection (alias phase sensitive detection or synchonous demodulation) can be performed this way:
