There is a simple switching sensor which will be wired to a circuit by a BNC cable as shown in the above illustration.
As you see, when the switch is ON the potential at the point "A" will be high; and when the switch is OFF the potential will be zero. Pulse freq will vary from 1Hz to 40Hz.
For some reasons, I need this ON-OFF pulse output to be sharp and clean. So I want to take the point "A" as an input to a circuitry(Schmitt trigger) and obtain a better output.
I need advice when designing a Schmitt trigger circuit which satisfies the following expectations for the output pulse:
It shouldn't bounce, it should be immune to noise and it should be as sharp as possible(very short rising falling edges). And it should work for 5V to 12V Vcc range.
I would appreciate any generic circuit or idea.
