how to calculate time period a continuous time signal in real time (eg: signal coming from the ADC port of dSPACE controller).

I have a real time periodic signal (trapezoidal / triangular depending on the operating conditions). I want to measure the frequency of the signal in real time. I am using a hardware in loop setup and a simulink model.I want to measure the frequency or time period of the signal coming from the ADC block in the simulink model in real time.

I haven't tried it, but would the following URL's model be helpful?
