- Abstract:
- Phase shift measurements are nowadays typically made in programmed measurement systems. Many of them are realized as virtual instruments, so called VI’s. There are many algorithmic methods of phase shift measurements described in the literature, but sometimes these methods are complicated. In this paper an idea of a simple method of phase shift measurement has been presented. The method uses derivatives of measurement signals and inverse trigonometric functions. A simple function allows calculating of the measured phase shift. The method has been implemented as a virtual instrument using the LabVIEW packet. The implementation is very simple and the virtual instrument can become a part of a more complicated measurement instrument. The inaccuracy of the phase shift measurement is maximal 3 deg. It is not very accurate instrument, but in some applications the accuracy can be accepted.
