  1. 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?
  2. 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 simple phase measurement.vi
