pulse-code modulation emerges from quantization.
Mechanism: PCM is sampling plus quantisation written as numbers.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Directly enables 2 concepts; following enables/causes relations, 2 concepts are downstream across 6 disciplines.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no key date stored · 5 of 5 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 5 → 17 → 61 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 5 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
What builds on this
1 concept build on this directly, 1 in total, across 3 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Digital audio, Quantization noise and Pulse-code modulation.
Through this lens it connects to Noise and Sampling.
