3. COMMUTATIVE LAW
a) Any binary operation Which satisfies the following
expression is referred to as commutative law.
EXPRESSION:- 1. A.B=B.A
2.A+B=B+A
b) Commutative law states that changing the sequence of vari
does not have any effect on the output on a logical circuit.
4. This law states that The order in which the
logic operations are perform is irrelevant
as they are effect in the same.
EXPRESSION:- 1.(A.B)C=A(B.C)
2.(A+B)+C=A(B+C)
5. Distributive Law states that the multiplication of two
variables and adding the result with a variable will result in
the same value as multiplication of addition of the variable
with individual variables.
Condition:- A.(B+C)=A.B+A.C
6. These law is used in AND operation
That for they called AND LAW.
1.A .0 = 0
2.A . 1 = A
3.A. A = A
4.A.A=0
7. These laws use the OR operation. Therefore they are
called OR laws.
1. A+0=A
2. A+1=1
3. A+A=A
4. A+A=1
8. This law uses NOT operation. It state that double
inversion of variable results in the original variable.
EXPRESSION:- A=A
