Finding period T from a square signal in Simulink

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.

Hi guy

I would to find the period of a Signal in Matlab Simulink. How do we do that. i really need your help. it is very urgent.Thanks in Advance

@Franck Joel Simo - did you find the answer of these? I need same help

Answer 1

[Mark McBroom]

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?

Answer 2

[Marek Andrzej]

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.
