Hi,
I'm doing an analog electronics project now, and the aim is to use signals from two speakers, and receive both of them with one microphone.
The signals that are given by the speakers are signals of different frequency ranges, and have different voltage offsets.
I am interested in finding the difference between the DC offset value of these signals.
However, as far as I've learned, if I receive both of them with an electret microphone and filtered them, its output removes all information about the DC offset value,
so how could I be able to preserve those values? Is there some other way to do this? (Using antennas, infrared sensors or LEDS etc is also possible)
NOTE: We HAVE to use two transmitters and one receiver.
