10. Boolean algebra methodology includes the following except
The logic operations are written in the form of a Boolean expression.
From the given truth table, a Boolean expression can be obtained which may not represent a simple circuit having minimum number of gates.
The Boolean expression may then be simplified to get a digital circuit having minimum number of gates
—>> The Boolean expression may then be simplified to get a Analog circuit having maximum number of gates
