Definitions

In plain terms

MAMA uses changes in estimated phase to vary its smoothing rate.

Technical

The phase convention, units, quadrant handling, unwrapping, clamps, delays, invalid states, and warm-up must be frozen.

Scope

Phase estimates can be unstable during warm-up or weak cyclic structure.

Examples

  • A governed lesson uses Instantaneous Phase only with declared inputs, timing, parameters, and edge-case behavior.

Common misconceptions

  • Phase estimates can be unstable during warm-up or weak cyclic structure.

    Limits: The abstract alone is insufficient for code parity; exact coefficients, state, clamps, and warm-up require a pinned implementation contract.
