8. LOGIC GATES
A logic gate is an electronic circuit which makes
logic decisions
BASIC LOGIC CIRCUITS : NOT,AND,OR
Gates are blocks of hardware that produce signals of
binary 1 and 0 when logical input requirements are satisfied

0+0 = 0
0+1 = 1
1+0 = 1
1+1 = 10
Binary addition
Half adder is a arithmetic circuit that adds two numbers and
produces a sum bit (S) and carry bit (C) as the output
A B C S
0 0 0 0
0 1 0 1
1 0 0 1
1 1 1 0
23. Half adder is a arithmetic circuit that adds two numbers and
produces a sum bit (S) and carry bit (C) as the output
The half adder can add only two input bits (A and B) and
has nothing to do with the carry if there is any in the
input
That means the binary addition process is not complete and
that’s why it is called a half adder
