How do I unwrap a phase in Excel?
Menu Path: Trace > Format > Format: Selecting the Wrap Phase or Unwrap Phase trace format displays wrapped or unwrapped phase for the active trace.
What is unwrap phase?
Phase unwrap or unwrap is a process often used to reconstruct a signal's original phase. Unwrap algorithms add appropriate multiples of 2π to each phase input to restore original phase values, as illustrated in the diagram.
How does unwrap work?
Whenever the jump between consecutive angles is greater than or equal to π radians, unwrap shifts the angles by adding multiples of ±2π until the jump is less than π. If P is a matrix, unwrap operates columnwise. If P is a multidimensional array, unwrap operates on the first dimension whose size is larger than 1.
What is phase unwrapping algorithm?
Phase unwrapping ensures that all appropriate multiples of have been included in . We defined simply as the complex angle of the frequency response , and this is not sufficient for obtaining a phase response which can be converted to true time delay.
