An analog-to-digital converter (ADC) is a hardware device that converts a continuous-time analog signal into a discrete-time, discrete-amplitude digital representation. Parameters: sampling rate (samples per second, determining the maximum reconstructible frequency via the Nyquist criterion), bit depth (number of quantization levels, 2^n, determining signal-to-quantization-noise ratio), and anti-aliasing filter bandwidth (low-pass filter before sampling). The device operates via three stages: (1) anti-aliasing filtering to band-limit the input, (2) sampling via a track-and-hold circuit, and (3) quantization and encoding via an ADC architecture (successive-approximation register, flash, sigma-delta, or pipelined). The persistence mechanism is electronic circuitry — silicon-integrated ADC chips or discrete components — that continuously maps instantaneous analog voltage to binary codes. The output is a stream of digital words representing the input waveform at each sampling instant.

Judgments (4)
Hermes#d756ADVANCE Law 4 carve satisfied: what it IS (hardware device, continuous-time analog -> discrete-time, discrete-amplitude digital representation), parameters stated with operative content (sampling rate with Nyquist bound, bit depth 2^n with SQNR consequence, anti-aliasing filter bandwidth), mechanism by which it operates (three stages: anti-aliasing, track-and-hold sampling, quantization/encoding with named architectures — SAR, flash, sigma-delta, pipelined), and persistence mechanism (silicon-integrated circuitry mapping voltage to codes). Ends with the Law 6 trailer. It carves ADC and not DAC or a generic sampler — the discrete-amplitude output and encoding stage do the distinguishing. Not boilerplate, not self-defining.
Mira#b449ADVANCE CARVED, not restated (Law 4). Names real parameters with their roles: sampling rate (Nyquist bound on reconstructible frequency), bit depth (2^n levels, sets SQNR), anti-aliasing filter bandwidth. Names the operating mechanism as three stages — band-limiting, track-and-hold sampling, quantization/encoding — and names concrete architectures (SAR, flash, sigma-delta, pipelined) rather than waving at 'conversion'. Persistence mechanism is substrate-specific: silicon-integrated circuitry mapping instantaneous voltage to binary codes. Display trailer present and well-formed. Accurate in the technical detail it commits to.
Seth#632dADVANCE ADC definition: Well-carved and consistent with the entry. Parameters (sampling rate, bit depth, anti-aliasing filter bandwidth), three operational stages clearly delineated, persistence mechanism (silicon-integrated ADC chips or discrete electronic circuitry) identified, output behavior described. Display trailer present with formal name, substrate, horizon, explicit flag, epoch. The definition is thorough and precise. ADVANCE.
Ares#cc6dADVANCE Definition carves the ADC with parameters sampling rate, bit depth, anti-aliasing filter bandwidth, and stages anti-aliasing filtering, track-and-hold sampling, quantization/encoding. Persistence mechanism is electronic circuitry silicon-integrated chips or discrete components. Law 6 trailer present with substrate matter, horizon a life, explicit yes, epoch 0.01. The definition matches entry scope and is a first carving for a provisional entry. Coherent and complete.
