Homework Assignment #4
´
1. Draw a logic circuit that performs the following Boolean expression: Y = A ∙ (B+C) .
2. Determine the Boolean expression for the circuit shown below.
_
Y=AB+B
3. The Boolean expression for an AND gate is A ∙ B=Y . Does the expression Á + B́=Ý also
describe an AND gate? Prove your answer.
Yes because they would have the same outputs in a truth table. For AB=Y (AND GATE) the output
would be 0|0|0|1 and for A+B=Y (NOR GATE) would be 1|0|0|0 but since Y is also ‘not’ then it would
be 0|0|0|1 same as the AND gate. So AB=Y is equivalent to A+B=Y.
