Lab 9

This lab was pretty interesting as far as learning further how to integrate excel into data management and overall collection. It was cool to realize how much an average person can do with the help of a computer, if everyone knew how to use these tools well, the jobs of many people such as accountants and things like that would easily be replaced. Also, modeling is a cool feature that can be done simply in excel as well. Being able to trace graphs with the simple click of the button is a great tool.

Lab 8

Understanding excel and other spreadsheet programs is very useful in the field of statistics and the analysis of data. These programs help by allowing quick sorting techniques and efficiant ways to compute different algorithms.

Lab 7 part 3

In this circuit, if one output is true or "1", then the other one is always true or "1" also. DeMorgan's law is true because both of the outcomes are the same on either output.

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.
