I wonder if some kind of discrimination could be implemented by measuring pulse width instead of it's height after pulse?
I tried to implement 16F877 code which measures pulse length with 16bit counter and dumps the result to rs232.. In my test case 555 was feeding the pulse through Lm318. Result was some noise width the pulse length.. maybe LM318 is not the correct choise. Any suggestions for better amplifier?
Well there weren't any noise capacitors anyway..
Several points to measure pulse width may be setup with trimmers.

Below is a little simulation with just LM318.
Simulated PI-pulse is red one.
Blue and red signals are different points of pulse width.
This needs to be tested with real PI pulse.
Any comments? Or is this a dead end approach?
