Test 1

Question 1

By now you should know enough LabVIEW to perform a fairly rudimentary operation. I am writing this in pseudocode so you should be able to follow. This may seem hard or dumb to you, but it contains the basics I have covered in these previous sections, and give you an idea of how to convert thought to what to do. Also you will probably use these techniques in many data analysis applications.
First INITALIZE a 1-D array with 5 elements of zero
WHILE the END OF FILE has NOT been reached

• IF the data is greater than one(1) and less than two(2) INCREMENT index 0 by 1
• IF the data is less than one(1) OR greater than or equal to two(2) DECREMENT index 1 by 1
• IF the data is equal to one(1) ADD index 0 and index 1 to index 3

The data file you will need is here. Simply copy it into a notepad and save it as a text file.

The way I did it is only one way, there are much harder ways and probably some simplier ways. If you have no idea what is going on, I would really appreciate you E-mailing me, so I can help resolve the problem.

Your results should look like this:

The result of this silly program is	20.0	-27.0	0.0	-1.0	0.0

Question 2

Here is a good thought and real life problem
You are building a refrigerator and need to keep the temperature between 35^oF and 40^oF. Now to economize, you want the compressor to start if the temp is above 35^oF, then stop and only start again when the temperature has reached 40^oF and continue until ir reaches 35^o, and so on until you tell it to stop. Here is a graph to illustrate the idea.

Programming tips:

• If this were a real life problem you have to solve, the compressor wouldn't need to be updated every second, so you would insert a time delay to slow the program down
• You will need a shift register, case structure, loop, and Boolean operators.
• Before you try to tackle the problem, think it through. Break down your thought process to the simplest leval so the computer will understand.
