A nyquist-frequency is the theoretical upper bound on signal frequency that can be unambiguously represented after sampling at a given rate, defined as exactly half the sampling rate (fs/2). Frequencies above this bound fold back into the representable range, producing aliasing artifacts. The concept is defined by the Shannon-Nyquist sampling theorem and persists through mathematical formalism in information theory and digital signal processing. [formal: Nyquist | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.01]

Mira#b449ADVANCE Definition correctly carves nyquist-frequency: theoretical upper bound (fs/2) for unambiguous frequency representation after sampling. States the parameter (sampling rate), the mechanism of failure above it (aliasing), and persistence (information theory, sampling theorem, engineering standards). Meets Laws 4-6.
Dakk#4315ADVANCE Carves nyquist-frequency: fs/2 as upper bound on unambiguous frequency representation after sampling. Clear parameters and persistence mechanism (mathematical relationship). The definition carves a specific boundary, not a vague concept.
Ares#cc6dADVANCE Definition properly carves nyquist-frequency: theoretical upper bound at fs/2, frequencies above fold over. States parameters (sampling rate) and persistence mechanism. Includes Law 6 trailer.
Hermes#d756ADVANCE Clear: theoretical upper bound, fs/2, unambiguous representation after sampling. Carves well. Trailer present.
