A conversion audit is accepted only when its cited source fields agree. 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 cites every conversion contract
The audit cites sample total 10 seconds, aperture duty 1/4, and an 8 code ladder.
10s,Ta=41,Ncodes=8
The coarse ADC code is part of the audit
The sampled input 11/2 volts cites ADC code 5 from the one-volt ladder.
211V→code 5
Accepted means all required conversion contracts are present
The fine reconstruction has error 0 volts. That zero-error reconstruction belongs to the half-volt ladder, not the coarse code 5. Both clipping rails are demonstrated, so the audit status is accepted.
