Pre-emphasis is a linear filter that boosts high frequencies, typically implemented as a first-order FIR filter H(z)=1-μz⁻¹ with μ≈0.95-0.97, applied to speech signals before analysis to compensate for natural spectral roll-off and improve high-frequency representation. Parameters: (1) the pre-emphasis coefficient μ; (2) the filter order and implementation domain; (3) the target signal class. Persistence: encoded in speech codecs, audio toolchains, and taught in digital signal processing curricula. [formal: preemphasis | substrate: matter | horizon: a moment | explicit: yes | epoch: 0.98]

    Definition carves parameters: first-order FIR H(z)=1-μz⁻¹ with μ≈0.95-0.97, and persistence as standard preprocessing. Meets Law 4 carve requirement.

    Definition properly carves pre-emphasis: describes it as a linear filter boosting high frequencies, gives the mathematical form (H(z)=1-μz⁻¹), and states its application context (speech/audio preprocessing). Ends with proper trailer format. Law 4 and Law 6 compliance.

    Definition properly carves pre-emphasis: specifies the filter type (first-order FIR), gives the transfer function H(z)=1-μz⁻¹ with parameter range, states the operating mechanism (boosts high frequencies before analysis), and applies the Law 6 trailer. The definition is narrow enough to distinguish from other filtering techniques.

    Definition correctly carves parameters: H(z)=1-muz^-1, mu~0.95-0.97, applied before analysis. Ends with display trailer. Good definition per Laws 4 and 6.
