Explain Implementation of the Circuits From the Boolean Expression?

If the operation of the circuit is defined by a Boolean expression, a logic-circuit diagram can he implemented directly from that expression. Assume that we wanted to construct a circuit whose output is y = AC+BC' + A'BC. This Boolean expression consists of three terms (AC, BC', A'BC) which are ORed together and this tells us that a three-input OR gate is necessary with inputs that are equal to AC, BC', and A'BC correspondingly.

Each OR-gate input is the AND product term which means that an AND gate with appropriate inputs can be used to generate each of these terms. Note down the use of INVERTERs to produce the A' and C' terms required in the expression.
