wrapped phase

Wrapped phase is a way of representing a cycle of angles or phases that repeats every 360 degrees (or 2π radians). Imagine measuring angles with a protractor, but only recording values from 0 to 360 degrees. When the true phase exceeds this range, it "wraps around" back to zero, causing a jump from high values to low ones. The wrapped phase shows these angles within the 0–360° (or 0–2π radians) interval, but it doesn't reveal how many times the phase has fully cycled. To get the true phase, you need to "unwrap" it, adding the full cycle counts to the wrapped values.
