Prelab-5 Submission Requirements:  Convert/save this Prelab-5 Worksheet as a .pdf file with a filename as follows: If Prelab is done individually: “Prelab-5_FirstName_LastName.pdf”. If Prelab is done in a group: If you have been explicitly instructed by your lab instructor to perform the Prelab exercises in a group, then save this Prelab-5 Worksheet as a .pdf file with a filename following the convention below: Let’s consider that two students are doing the prelab in a group. Then the filename should be: “Prelab-5_FirstName of Student 1_FirstName of Student 2.pdf”. For example, if name of the two students are Tom Cruz and Morgan Freeman, respectively, then the Prelab-5 Worksheet file should have the following name: “Prelab-5_Tom_Morgan.pdf”. Similar file naming convention should be followed to properly name your LTspice schematic file . Improperly named files may be subject to point deductions.  Prelab Submission Checklist: There should be two files submitted for your Prelab-5 assignment. The Prelab-5 Worksheet (.pdf) and the LTspice schematic file (.asc).  Check with your lab instructor about specific instructions on how to submit your Prelab files for assessment and grading. Prelab Score: This prelab contributes to 30 points toward Lab 5 (each Task in the Prelab is worth 10 points). In-lab hands-on work will contribute to 70 points (Lab 5 total is 100 points). 8 | P a g e
