see example attached (R2015a)
the output of the last bloc gives you the period measured between two rising pulses (generated by the hit bloc)
the sampling frequency is 1000 Hz (dt = 1e-3)

Hello Ahmad,
A built-in block that determines the switching frequency of a signal is not available in the Simulink library. This previously answered question may help you get some insight on this.
You can also look into this Spectrum Analyzer block to see if it suits your needs.
