Lab 8



Lab 8 was an intro to using Excel. I have used excel in the past so I knew a little bit about using it.
I learned that you can import text files instead of typing them in. This is nice to know because it saves alot of time. I also learned how to sort data, I knew you could do this, but I never knew how. I also learned about the sigma symbol. This symbol is very usefull. You can sum, average, count, and many more functions. I am very fimiliar with charts in excel. That's what I have used Excel for in the past.

Lab 7-Task 3


Lab 7-Task 2




This circuit has a XOR gate, then goes to a NOT gate. The XOR gate means that it is A or B and not both A and B. This means that it is true only if it is either A or B, but not both of them. The not gate makes it true if A and B are both the same.
