Implementation of logic functions using gates
Follow the steps given below to draw the logic diagram for the given logic function.
1. For a function in Sum-of-products form, the final output gate is an OR gate. For a
function in Product-of-sums form, the final output gate is an AND gate.
2. Realize the (.) function using AND gate.
3. Realize the (+) function using OR gate.
4. Realize the complement ( ) function using NOT gate.
Example
1. Draw the logic diagram for the following logic function.
Y = ( . B) + (A .) + ( . C)
2. Draw the logic diagram for the following logic function.
Y = (A + B + C) . ( + )
3. Draw the logic diagram for the following logic function.
= +
= +
