first step is to identify the overall type of circuit. For example, the Boolean expression
A B C D can easily be recognized as a four-input AND gate. To convert this expression to
a logic diagram, draw a logic symbol for an AND gate and label the inputs A, B, C, and D.
The completed conversion is shown below.
Convert the Boolean expression below to a logic diagram and indicate the inputs.

When converting from a Boolean expression to a logic diagram, the first step is to identify
the overall circuit type. This does not present much of a problem with first- order logic, but a
thorough understanding of the basics is necessary before proceeding to the more complex
circuits. For example, the Boolean expression A+B+C+D is identified as an OR gate with
four inputs. All that is necessary to convert this expression to a logic diagram is to draw a
