Hi
Help please...
I need a circuit that can detect a nearby tuned circuit...
The object with the tuned circuit embedded within it is made to look like a
rock
The 'rock' is dropped into a detection coil which will pick up the resonant
frequency to identify the type of 'rock'
There will be three types of rock each with it's own resonant frequency.
I am an electronics engineer but I have little experience with RF.
I need a relatively simple circuit that can give me three logical outputs
one for each rock type.
This is for an educational facility and I am not commercially involved.
Any help much appreciated.
