period of 1d array

[tzj]

I need to measure the period of a 1D array of doubles. This data is taken from an encoder that puts out a square waveform. The problem is that the period changes every 1 cycle and I need to be able to accurately measure the period of each cycle. What function can I use to get this data?

Thanks!

Do you have a small data sample you can post?  Regards, -SS

I can think of 2 ways off the top of my head:

• Use the Pulse Measurement VI to return to you the pulse widths.
  
• Use the Transition Measurements VI to basically get the same thing.

The problem is that the data acquired is not a waveform but a 1d array. I have attached some sample data.

A 1D array can be turned into a waveform:




What is the second column in your data?

Sorry about that, the second column is another set of data from another sensor. I will give this a try and see what results I get. Will post any other problems here.
