Calculation method
Calculation method
Interval center and group delay (seconds)
Unwrap successive phase jumps into [−180,180], then −delta phase/(360 delta frequency).
Unwrapped phase (degrees)
Shortest successive increments; exactly 180 degrees follows positive-180 convention.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Frequency-phase data, unwrap convention. Returns Group-delay curve. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Strictly increasing frequencies (Hz): minimum None, maximum 1000000000000.0. Measured wrapped phase (degrees): minimum None, maximum 1000000000000.0.
