The Boolean expression (AB+C) D is identified as an overall two-input AND gate. Note
that the quantity (AB+C) which indicates a two-input OR gate must be treated as a
separate quantity when converting from the Boolean expression to a logic diagram. The
expression is converted to a logic diagram, following a step-by-step procedure as shown
below.
Step 1. Identify the overall type of circuit.
a. (AB+C) D-this signifies a two-input AND gate.
b. The logic AND-gate symbol with two inputs is shown below.
Step 2. Identity the quantity AB+C.
a. AB + C-this signifies a two-input OR gate.
b. The logic OR-gate symbol with two inputs is shown below.
