Thus if we had a sampled analogue input of 8 V, the digital output
would be 000 for a 0 V input and would remain at that output until the
analogue voltage had risen to 1 V, i.e. 1/8 of the maximum analogue
input. It would then remain at 001 until the analogue input had risen to
2 V. This value of 001 would continue until the analogue input had risen
to 3 V. The smallest change in the analogue voltage that would result in
a change in the digital output is thus 1 V. This is termed the resolution
of the converter.
