Like OR and AND operation, the NOT Operation is also an important function in the digital electronic circuit. It is denoted by a bar. The binary not operation is also known as not function or complement function or bit invert function.
The not operation has only one input and one output. The input and output of the not operation are either zero or one. In the negative logic, 0 stands for high and 1 stands for low signals. The not operation will always produce a 0 out if their input is 1 and if their input is 0 then it produces the output, 1.
Example: Consider the word statement Z = A Not A. In boolean algebra it is expressed as:
When the value of x is equal to 0 the value of z is equal to 1. When x is equal to 1 the value of z is equal to 0.
