Hi everyone! I'm new to the forums but there seems to be alot of knowledge and resources here.
I have a project for school that I'm working on and I am having trouble tackling one part.
I need to detect a 10kHz frequency that is coming from another device that is transmitting the signal thru a wire about 40ft long.
My problem is actually detecting the signal. I have tried, with no success, using a condenser microphone fed into an opamp then a bandpass designed to peak at the 10kHz frequency. then I was going to use a frequency to voltage converter to input into the microcontroller.
does anyone have any other ideas about how to actually pick up the signal? This is where I am really stuck as I don't know much about antennas and signals.
Thank you for any help you can provide.
