Unwrapped phase

The unwrapped phase is not restricted to the wrapped range, and has no jumps. The unwrapped phase is computed from the wrapped phase by changing absolute jumps greater than 180 degrees to their 2*180 degrees complement.

Note: If the phase curve is not smooth, the computation of unwrapped phase may give a wrong result. Because of this, it is not recommended to select unwrapped phase when displaying the phase of a room measurement.
