Section 3.4
NOT Operation

The NOT operation is unlike the OR and AND operations in that it can be performed on a single input variable. For example, if the variable A is subjected to the NOT operation, the result x can be expressed as

x = A'

where the prime (') represents the NOT operation. This expression is read as:
x equals NOT A
x equals the inverse of A
x equals the complement of A

Each of these is in common usage and all indicate that the logic value of x = A' is opposite to the logic value of A.

The truth table of the NOT operation is as follows:

1' = 0 because NOT 1 is 0
0' = 1 because NOT 0 is 1

The NOT operation is also referred to as inversion or complementation, and these terms are used interchangeably.
