Lab 7 part 2

This Circuit is fairly simple if you take just a second to look at it. First the two switches run into a XOR box. This box returns a "0" if either of the two are the same. Then the circuit passes through a NOT box. This NOT box essentially just flips the result from "0" to "1" or positive to negative. So in essence, all the circuit does is register if the two switches are the same, if they are then it returns a "1" in the output, if they are different then it returns a "0" in the output.
