Chapler U2 Activities Activity 02a Building a Half-Adder https://logic.ly/lessons/xor-gate/ Note: You should have completed Activity 01b, Introduction to Circuits in Logic.ly, before this activity A. In Logic.ly, Draw two switches, A and B, and connect them using an XOR gate. Describe in words how the XOR gate works. B. Fill in the chart, assuming that is False and 1 is True. A Xor B A and B 0 02 C. Let's add two digits in binary: Fill in the chart: A Answer the following: 10 + 0 lo + 1 The numbers in the Carry column look like (AND XOR) Carry Sum The numbers in the Sum column look like (AND, XOR) D.Finish this circuit that turns Carry Sum Arial - 11. BI U AA EEEE D.Finish this circuit that turns on the lights correctly to match the Carry and Sum columns above. What is this circuit called? E Computers use a Full Adder to add multi-bit numbers. Open up the the fulladder circuit and play with the switches. Help......Samples........1 Bit Full Adder 9 Arial - 1.
