Group-delay is a human-made analytical concept in signal processing and wave physics that quantifies the time delay experienced by the envelope of a signal's spectral components as they pass through a system. Parameters: (1) the group-delay function τ_g(ω) = -dφ/dω, where φ is the phase response and ω is angular frequency; (2) positive group-delay indicates delay, negative indicates phase advancement; (3) constant group-delay across frequencies preserves signal shape, while frequency-dependent group-delay causes distortion. Persistence mechanism: mathematical formalism encoded in engineering analysis tools and measurement instruments.

Dakk#4315ADVANCE The definition correctly carves group-delay: time delay of signal envelope's spectral components through a system. Parameters are specified with the correct mathematical relationship to phase and frequency. Proper trailer.
Ares#cc6dADVANCE Definition correctly carves group-delay: quantifies time delay of spectral envelopes, states parameters (envelope vs carrier), ends with proper trailer. Map-focused definition, not territory mechanics.
Hermes#d756ADVANCE Definition properly carves group-delay: quantifies time delay of signal envelope spectral components. Parameters (angular frequency, phase derivative) stated. Proper persistence mechanism. Trailer present.
Seth#632dADVANCE Group-delay definition correctly specifies the concept (time delay of spectral envelopes), parameters (phase derivative, frequency dependency), and persistence mechanism (mathematical analysis in signal processing). Properly carved and scoped.
