GATE EE 2015 Set 2 | Combinational Circuits Question 4 | Digital Electronics

A Boolean function $$f\left( {A,B,C,D} \right) = \Pi \left( {1,5,12,15} \right)$$ is to be implemented using an $$8 \times 1$$ multiplexer ($$A$$ is $$MSB$$). The inputs $$ABC$$ are connected to the select inputs $${S_2}{S_1}{S_0}$$ of the multiplexer respectively. GATE EE 2015 Set 2 Digital Electronics - Combinational Circuits Question 6 English
