1. ME 392 ME 392 23 January 2012 Week 3 Joseph Vignola

2. Assignment 2 Assignment 2 is due Friday, January 27 Please e-mail you submission as a single zip file that contains all the VIs you created for each problem and an MS Word file that explains what you did. I recommend that you make or use a MS Word template I posted one on the class webpage

3. Assignment 2 Assignment 2 is due Friday, January 27 The MS Word file should have a name like “ME 392 assignment 2 your name.docx”, The zip file should have a name like “ME 392 assignment 2 your name.zip” and The VIs should have names like “ME 392 assignment 2 problem 1 your name.vi”. The MS Word file should have your name, your partner’s name the assignment name, the class name, and the date. You should also include some brief explanation of what you did for each problem.

4. Things to Remember Signals carry information not power Switch partners for each lab and assignment Share code only with one lab partner Do not share text with anyone

5. Things to Remember In the first assignment you learned how to make manipulate number and strings in LabVIEW display items Sort numbers Use programing structures

6. For Assignment 2 You will work with arrays of numbers Pass a signal out and back into the 2120 box Save data to a file Taken from NI.com

7. For Assignment 2 For problem 1 I used the random number generator to make a random array

8. For Assignment 2 For problem 1 I used the random number generator to make a random array

9. For Assignment 2 For problem 1 I used the random number generator to make a random array Then made a sub-vi of that I posted the sub-vi called random 2d array in a zip folder called ME 392 VIs on the class web page.

10. For Assignment 2 For problem 1 I used the random number generator to make a random array Then made a sub-vi of that I used a “flat sequential structure” to control the sequence of things that the program is doing First stuff

11. For Assignment 2 For problem 1 I used the random number generator to make a random array Then made a sub-vi of that I used a “flat sequential structure” to control the sequence of things that the program is doing First stuffSecond stuff

12. For Assignment 2 In the second box of the “flat sequential structure” I used a true / false “case structure” so that I could average either the rows or columns I also used “property node” so that I could control (turn no and off) what was being displayed make a “property node” for an indicator 1) right click the indicator 2) create 3) property node 4) visible

13. For Assignment 2 In the second box of the “flat sequential structure” I used a true / false “case structure” so that I could average either the rows or columns I also used “property node” so that I could control (turn no and off) what was being displayed make a “property node” for an indicator 1) right click the indicator 2) create 3) property node 4) visible Then right click the node and “Change all to write”

14. For Assignment 2, Problem 2 You will need to create and display a signal This is something that you will be doing a lot of this semester To make the signal that has noise I used the

15. For Assignment 2, Problem 2 You will need to create and display a signal This is something that you will be doing a lot of this semester To make the signal that has noise I used the…

16. For Assignment 2, Problem 2 You will need to create and display a signal This is something that you will be doing a lot of this semester To make the signal that has noise I used the… to make a signal and add noise

17. For Assignment 2, Problem 2 I used the curser and a right clicks to make controls for

18. For Assignment 2, Problem 2 I used the curser and a right clicks to make controls for the tone (the signal) the noise sampling parameters

19. For Assignment 2, Problem 2 I used the curser and a right clicks to make controls for the tone (the signal) the noise sampling parameters Then I made a graphical display from the front panel

20. For Assignment 2, Problem 2 I used the curser and a right clicks to make controls for the tone (the signal) the noise sampling parameters Then I made a graphical display from the front panel I then put all of this in a for loop so that I could generate the signal with noise some number of times…

21. For Assignment 2, Problem 2 I used the curser and a right clicks to make controls for the tone (the signal) the noise sampling parameters Then I made a graphical display from the front panel I then put all of this in a for loop so that I could generate the signal with noise some number of times and then the column averaging from the first problem

22. For Assignment 2, Problem 3 For this problem I would use the “DAC Assistant” to send a signal to the “BNC 2120” box and a second “DAC Assistant” to read the signal. Taken from NI.com BNC 2120

23. For Assignment 3 You will: Use handle graphics in Matlab Create, play and record signals using Matlab This is all explained in the Matlab notes that are posted in the class webpage
