Complete the truth table for the three-input AND operation below.

A NOT-operation circuit, also called an INVERTER circuit, produces the
complement of whatever is applied to its input. Two NOT (inverter)-logic symbols
are shown below.
The maximum number of inputs to a NOT circuit is one. The output is a 1 level
when the input is a 0 level; the output is a 0 level when the input is a 1 level. If the
input were labeled A, the output would be labeled Ā; if the input were labeled Ā, the
output would be labeled A. This logic symbol is called an inverter, because the
output is always the complement of the input. What is the maximum number of
inputs which may be applied to a NOT circuit?
