Computer Systems Lab 2 – 2 – Note that the sum outputs of the truth table correspond to those of the XOR gate, and that the carry outputs corre- spond to those of the AND gate. Thus the half adder may be implemented with only two gates, as shown in Figure 2. In the fi gure, G1 stands for a gate in IC number 1 (a 7486), and G2 stands for a gate in IC number 2 (a 7408). Construct the circuit as shown in Figure 2. Set SW2 and SW3 to the positions indicated in the truth table and record the light indications. DO NOT tear down the circuit after you have fi nished. You will need it for the circuit of Part 3.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
