Please show the corresponding truth table and function for each question. Also if you can, please use the software Logicly to contruct your circuits. Thank you!

1. Full adder and parallel adder. (35 points) a. Design a 1-bit full adder which has 3 inputs and 2 outputs; then, make it as an integrated cicuit. (20 points) b. Use your full adder to design a 4-bitripple-carry adder. You should have two 4-bit inputs and one 5-bit output. Showme the screenshot of your circuit with input values 11 and 9. (20 points 2. Full subtractor and parallel subtractor (35 points) a. Design a 1-bit full subtractor which has 3 inputs and 2 outputs; then, make it as an integrated circuit. Showme a screenshot of the original cir cuit. (20 points) b. Use your full subtractor to design a 4-bit parallel subtractor You should have two 4-bit inputs and one 5-bit output. Show me the screenshot ofyour circuit with input values 3 and 11 (20 points) 3. Design a calculator circuit which can perform either addition or subtraction on a 4-digit binary input and generate a 5-digit binary output. Your cir cuit should let the user decide if the operation should be addition or subtraction. Note: you can re-use your parallel adder and parallel subtractor circuits. (20 points)
