PLOTTING OF FREQUENCY VS.. TIME

[Krunal shah]

           Mainly I want to monitor and analyze real motion. For that I may get square pulses from the quadrature encoder. The frequency of these pulses will be proportional to the motor speed. I want frequency of these pulses should be plotted vs. time. So I can analyze the motor's motion trajectory. Also want the no. of pulses (counter value) at the different time. This will help me to find out the traveled distance at different time intervals.

Kind regards,

Krunal shah.

Hello Krunal,

Which acquisition card do you intend to use?

You can go through the following links for info on counter based frequency measurement:

I have attached an example program(taken from labVIEW examples) which might be of some help to you.
