How do you unwrap a phase in Matlab?
Q = unwrap( P ) unwraps the radian phase angles in a vector P . 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.
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.
