Standard Signal Processing Libraries#

Libraries for filtering, FFTs, smoothing, and basic transforms. Their mathematical behavior is stable, well‑characterized, and widely validated.

Dimensional Core (SET)#

• Spin: not relevant
• Elec: digital computation
• Temp: not relevant

Why Green‑Zone#

These libraries operate in a high‑coherence mathematical regime.
Their algorithms are deterministic, transparent, and substrate‑agnostic. They introduce no hidden inference layers.

Regime Notes#

• pos‑regime: clean signals, stable sampling
• Q‑regime: noise, quantization effects
• neg‑regime: aliasing, undersampling, unstable inputs

Alignment Notes#

Already aligned.
Only note: sampling assumptions must be explicit.
