I'm preparing for a lab where I will measure the frequency and amplitude of a tuning fork optically. From my setup, I will get a signal corresponding to the number of millimeters of displacement the tuning fork currently has. I expect this signal will look like a sine wave and that the amplitude will decrease over time.
This is the signal I will send to LabView via GPIB. It will probably have some noise. What is the best approach to find the frequency and amplitude of the signal?
How do I implement this in LabView?
There are some inbuilt examples in LabView, Please check "Find Examples"

Hope that helps...:)
