1. Using the “LogicWorks” tool, build a 1-bit full adder/subtractor that is made of only

NOR gates. Label all inputs as well as all of the outputs of the 1-bit full adder/subtractor.

2. Using the “LogicWorks” tool and using the 1-bit full adder/subtractor that you have built

in step (1), build a 4-bit ripple-carry adder/subtractor. Label all inputs as well as all of the

outputs of the 4-bit ripple-carry adder/subtractor. Use two “Hex Keyboard” devices under

the “Simulation IO” library to connect to the inputs of your circuit instead of using

“Binary Switches.”
