supply-audit-cites-every-source - Electronic Circuits XIII: Power, Rectification, and Regulation Step by Step

The final supply ledger accepts only a coherent source-bound chain. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The audit accepts only a coherent source chain

The transformer, rectifier, reservoir, regulator, and holdup ledgers are all cited by source. A copied final number is not enough.

\text{accepted}=(\text{reservoir pass})\land(\text{regulator pass})

Either failed gate rejects the supply audit

The accepted row has both gates true. A reservoir failure or a regulator failure is enough to reject the chain.

\begin{array}{c|c|c|c}\text{reservoir}&\text{regulator}&\Delta V_{\text{holdup}}&\text{audit}\\\text{pass}&\text{pass}&4\ \text{V}&\text{accepted}\\\text{fail}&\text{pass}&4\ \text{V}&\text{rejected}\\\text{pass}&\text{fail}&2\ \text{V}&\text{rejected}\\\end{array}

The accepted supply cites every source ledger

The capstone accepts only one coherent chain: transformer, rectifier, reservoir, regulator, load, waste, and holdup.
