I want an analogue circuit that check a voltage(V) with a reference voltage(Vt). When the voltage V<Vt, if (yes, it outputs a One and waits 2sec and again check V<Vt, if yes it output a one and check for a reset signal for One, if reset appears(1) it outputs a Zero & goes to the starting point), else (no, it output Zero and stay in the initial stage with continue checks whether V < Vt).

Need help. I'm new(beginner) in this field.

I suppose you can kludge up a 555 timer for a delay, but having a continuous monitoring situation can be valuable.
