Unformatted text preview: 4. Use the schematic editor to create a circuit with a single OR gate, plus input and output terminals. Use the logic simulator to show how the output changes for all input values. Hand in printouts of the schematic and the logic simulation run. 5. Using a truth table, demonstrate that: XY + YZ + XZ = XY + YZ + XZ 6. Using a truth table, prove DeMorgans Theorem for three variables: (XYZ) =X+Y + Z. 7. Draw a logic diagram that directly corresponds to each of the expressions shown below. ( a ) AB + A C D + A B D + A B CD ( b ) B + A C D ( c ) ( A + B + C + D )( A + B + C + D )...
