A converter is a purpose-built device — a hardware circuit, integrated chip, or firmware/software artifact — whose sole function is transforming a signal or quantity from one representational domain to another while preserving the carried information content across the transfer. Parameters: (1) input domain — the representational form of the incoming signal (e.g., continuous-time analog voltage, discrete digital codes, a given sampling rate); (2) output domain — the representational form produced (e.g., discrete digital codes, continuous-time analog voltage, a different sampling rate); (3) transfer law — the reproducible mapping relating input to output (sampling plus quantization, a quantization ladder plus reconstruction filter, a resampling kernel with interpolation and anti-imaging/anti-aliasing filtering, level or impedance transformation); (4) fidelity constraints — the bounds within which content is preserved (bandwidth, bit depth, jitter, error bound). Persistence mechanism: fabricated as silicon circuits or packaged as firmware and software libraries, distributed through electronics and software supply chains, maintained by the engineering discipline of signal processing, and replaced when the transfer law or fidelity target changes.

Definition
Why it is in scope
Human-made: a purpose-built device whose very function is transforming a signal or quantity across representational domains, persisting as a physical or software artifact with a reproducible transfer law.

Removal test: converter's accepted carve assigns it the sole function of transforming a signal (or the quantity a signal carries) from one representational domain to another. Remove the signal and there is nothing to convert — no input to the transformation, so the device has no operation left to perform and stops operating. Pinned sense: the signal as the input the converter's operation processes, not a generic conceptual need. Cluster precedent: stereo, audio-processing, and audio-engineering all carry accepted DEPENDS_ON signal on the same functional reading.

- digital-to-analog-converter← INSTANCE_OF
Law 9 specific-to-general, nearest kind: DAC's accepted carve is 'an electronic circuit or integrated chip that reconstructs a continuous analog voltage waveform from a stream of discrete digital codes' — input form: discrete digital codes, output form: continuous analog voltage, transformation law: quantization ladder plus reconstruction filter. That is precisely converter's carve (domain transformation preserving information content). No more specific kind node exists, so converter is the nearest accepted kind.
- analog-to-digital-converter← INSTANCE_OF
Law 9 specific-to-general, nearest kind: ADC's accepted carve is 'a hardware device that converts a continuous-time analog signal into a discrete-time, discrete-amplitude digital representation' — input form: continuous-time analog signal, output form: discrete-time/discrete-amplitude digital representation, transformation law: sampling plus quantization. Precisely converter's carve. No more specific kind node exists, so converter is the nearest accepted kind.
