how do i create a signal which is reset to zero every time the input signal increases of 1?

Hello everybody,

I need a Simulink model capable to take an input signal (for instance a discrete ramp) and to provide an output signal (true/false) that detects whenever the input signal increases of a value of 1, as shown in the attachment. For instance, the output signal could be a 0-1 signal or a staircase signal with step height =1.

thanks to all!

signal2 = diff(signal) == 1;

Hey Jan, thanks for your answer. I was not completely clear in my question and now i changed it a bit. I would like to implement a Simulink model. I think i need a switch (which detecs when the input has increased of a value of 1), a unit delay and a subtracting block, but I'm not able to arrange them efficiently

by the way, i found a solution with this:
