Dependencies

What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

Bit depthis part ofDigital audioEstablished

Open Bit depth →

bit depth is part of digital audio.

Mechanism: Bit depth is one of the two numbers (with sample rate) defining a PCM format.

Open Pulse-code modulation →

pulse-code modulation is part of digital audio.

Mechanism: PCM is the baseline uncompressed digital-audio representation.

Quantizationis part ofDigital audioEstablished

Open Quantization →

quantization is part of digital audio.

Mechanism: Quantisation is the amplitude side of turning sound into numbers.

Signal samplingis part ofDigital audioEstablished

Open Signal sampling →

signal sampling is part of digital audio.

Mechanism: Sampling produces the sample stream that digital audio is made of.

Structural role & consequence

Interpreted from the current atlas graph — what the connections mean, not just how many there are.

  • Currently dark in the atlas: no key date stored · 8 of 8 of its relations lack claim-level evidence.

    atlas representation · Describes the current Thinking OS representation, not the state of the world.

  • Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).

    structural · Structural graph analysis — not a claim of importance, causation or history.

  • Structural neighbourhood: 8 → 38 → 100 concepts reachable within 3 hops.

    structural · Structural reach — being reachable is not the same as being understood.

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

  • Its dependency reading rests on 1 foundation relation. structural
  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
