mzu: the unwrap phase vi needs an array of phase inputs, I am un sure how to extract this from a sine wave signal.

hooovahh: another method I could employ is to calculate the phase, to do this I would need measure the time delay between two real signals, could you offer any ideas on how to accomplish this?

Hi all,

I am quite new to LabVIEW, I am using it as a part of my final year project (in my mechanical engineering course)

There us one issue I am having huge difficulties with is phase measurement.

Essentially I am using sine wave signals (comparing two to find the diiference in phase) however I cannot measure the phase greater than 360 degrees. For example when the phase difference is say 420, the tone measurement gives a phase of 60 degrees. For what I am using LabVIEW for I will need to know the total phase 420.

Included is a simple vi showing this issue.

Does anybody know any solutions to this? Any help at all will be greatly appreciated.

Regards
