Redstone circuit that activates on short pulse and does not activate on longer pulse

Question

I made a circuit that activates on a long signal but I am missing one that activates on a short pulse and does not activate if the pulse time exceeds a certain pulse. Everything I made still activates on a longer pulse which is a problem as I only want one output in a one input system (see below for more details). I would like to have this as an adjustable circuit (minimum/maximum pulse length).

System details:

• 1 input
• 2 outputs
• Longer signal will output a certain signal (x) - this has been made
• Shorter signal will output a certain signal (y) - this is the problem
• Longer signal will not output the signal (y) - this is the problem as it currently does

Current system (very basic)

Answer 1

so i build a little crude thing that works, it needs improvement, but it will give the idea

section A is a timer, it counts how long of a pulse is allowed

section B is a falling edge mono-stable circuit

the 32 items in the hopper is so a stone button gets through, but a wooden one doesn't

so when the pulse from the input (between the buttons) and it ends after the clock, it will get cut off

but if its shorter then the clock, it will pass through the comparator facing the piston

note: this is the falling edge mono-stable circuit I used

hopefully I helped!
