1 LOGIC GATE
1.1. Logic Operations
In Boolean algebra, all the algebraic functions performed is logical. The AND, OR and NOT are the basic operations that are
performed in Boolean algebra. There are some derived operations such as NAND, NOR, EX-OR, EX-NOR that are also
performed in Boolean algebra.
1.1. NOT Operation
Symbol:

NOT
A ⎯⎯⎯ → A or A (Complementation law)
and A = A Double complementation law
Truth table for NOT operation
Input Output
A Y=A
0 1
1 0
A NOT gate can be represented using switch whose circuit representation is shown in figure below.
