The question comes up how does a detector work? The short answer is it requires a nonlinear device or as some say a distortion. So where to begin? First we need a signal to observe the effect on a component.
I send a pulse across a resistor and I have that pulse impressed across the resistor.
I send the pulse through a capacitor and across a coils and display the input. Clean square wave pulses.
Look at the output.
One way to check the 'Q' of a coil is to ring it and count the pulses and the wave decays.
You can check the coil self resonance using this method too.
The main object is to observe the coil will ring if pulsed.
end part 1.
