rpm of a continuous signal

[Lior_Bachar]

hello,

I have a simulated signal of a 10 teeth gear (lets say sine wave). I need to display the speed (in RPM) for every period (of  the gear). I tried to use Peak Detector, but I dont know how to define this VI to stop counting peaks every 10 peaks, so I could calculate the time elapsed in the current period. 

what can I do ?

thanks.

Use the Extract Single Tone Information VI on the Signal Processing palette to measure the frequency.  Multiply by 60 and divide by the number of teeth on the gear.
