Software Waveforms download for free from Digilent http://store.digilentinc.com/waveforms-2015-download-only/ Note: you cannot open Waveforms unless your Analog Discovery is connected to your laptop/pc. MATLAB

Connecting Analog Discovery to Waveforms To install Waveforms on your computer follow this link for the 2015 version: https://reference.digilentinc.com/reference/software/waveforms/waveforms-3/start Once you have installed Waveforms on your computer, connect your Analog Discovery device to your computer and open Waveforms. You should see this in the bottom side of Waveforms: The serial number on your device will be different, just make sure that your device is recognized in Waveforms.

Supplies/Hardware/Software MATLAB is available for immediate use on my.apps.utep.edu ETC will install software for you in E351, 3 rd floor between the Engineering Building and the Classroom Building. MATLAB takes about 25 to 60 minutes to install, depending on the laptop, and uses 9GB of space. MATLAB needed by next week s Lab, please bring laptop to class.

COMMUNICATE WITH TA s AND INSTRUCTOR COMMUNICATE WITH TEAM MEMBERS Problem Solving Methodology HOW DO WE SOLVE COMPLEX ENGINEERING PROBLEMS? UNDERSTAND PROBLEM: WRITE PROBLEM STATEMENT/PROCESS GATHER INFORMATION TO SOLVE PROBLEM: DATA/UNIT CONV DEVELOP/IDENTIFY STRAGEDY TO SOLVE PROBLEM: UNIT ANALYSIS SET UP SOLUTION AND SOLVE PROBLEM: ATTEMPT SOLUTION CHECK SOLUTION: VARIOUS METHODS, DOES IT MAKE SENSE

Unit Analysis Source: https://www.wired.com/2010/11/1110mars-climate-observer-report/

Problem Solving You will follow these steps for all calculations: 1. Write QUESTION/PROBLEM STATEMENT. 2. Write original EQUATION. 3. SOLVE for desired variable 4. Substitute VALUES and UNITS 5. Add the necessary UNIT CONVERSIONS 6. CANCEL OUT unit conversions and IDENTIFY units left. 7. CONFIRM units 8. CALCULATE answer and UNDERLINE solution.
