I am looking for the period T of a square wave, in Simulink (variable width). Not from Scope block, I need it for further math operations.

Feed signal into triggered subsystem. Configure triggered subsystem to active on rising edge. In triggered subsystem, use a Digital Clock and Memory block to compute time between current and previous rising edge.

Thank you for the answer! I tried but I don't really know where to connect what. Should I be feeding the signal into the trigger slot and substitute "in" with the digital clock?

Ok I got it. Was a bit trickier. The time in the memory block was being added up so I branched two memory blocks in a series (to have the previous time) and subtracted them. This way the before iteration minus before before iteration is my output. Ergo the time between rising edge.
