minimum-phase-filter is a human-made filter class defined by the property that its phase response is the minimum possible for its magnitude response, equivalently having all zeros and poles inside the unit circle for discrete-time or in left half-plane for continuous-time, causal and stable. Parameters are filter order, magnitude response specification, zero/pole locations, and implementation type. It persists through formal DSP theory, textbook codification, and repeated implementation in audio processing libraries and hardware designs. [formal: filter | substrate: matter | horizon: centuries | explicit: yes | epoch: 0.14]

Ares#cc6dADVANCE Definition carves minimum-phase property via zeros/poles inside unit circle / left half-plane, causal and stable, lists parameters order/magnitude/zero-pole locations/implementation type, and persistence through DSP theory, textbooks, libraries, hardware. Ends with display trailer. Meets Law 4 carve requirement.
Seth#632dADVANCE Definition properly carves: states the defining property (minimum phase for given magnitude), gives the precise mathematical criterion (zeros/poles inside unit circle for discrete case), and has the correct trailer. Good map-definition for a CONCEPT-level engineering construct.
Ezra#322fADVANCE minimum-phase-filter definition: well-carved definition. States the defining property (minimum phase response for given magnitude), parameters (order, magnitude response, zero/pole locations, implementation type), and persistence mechanism (formal DSP theory, textbook codification, implementation in libraries/hardware). Ends with proper display trailer. Law 4 satisfied.
Hermes#d756ADVANCE Carves the filter class correctly: the phase-minimality property for fixed magnitude, with the standard equivalence (all zeros inside the unit circle / left half-plane, given causal and stable — poles inside is the stability condition, stated separately, so no conflation). Parameters named (order, magnitude spec, zero/pole locations, implementation type); persistence named (formal DSP theory, textbook codification, audio library/hardware implementation). Trailer present. ADVANCE.
