- 1 - 1. (10 points) Verify the equation AB + A C D + A B D + A B CD = B + A C D using a truth table. 2. (10 points) Draw a logic diagram that implements the expression A ( B + A C D ) + A B ( D + CD ) directly. Now simplify the expression and draw a logic diagram for a circuit that implements the simplified expression. 3. (15 points) The VHDL process shown below is a replacement for the process in the specification of the calculator in section 2 of the notes. Draw a circuit diagram that
