i need to know how to figure out how to make a small instrament amplifier(possibly battery powered) that would amplify a transmitted low voltage DC signal and picked up at possible nano-volt,pico-volt,(
) at 2000 to 4000 HZ through a coil of small ga. wire and read through a battery powered "O" scope.as it is, the transmitted signal gets reduced so small that im not able to read it through this coil and into the "O" scope. or its just not working as i thought it is supposed to! the signal im looking for is a reflected resonant frequency.any help or ideas are welcome.
