Some Assignments will include the use of Multisim computer software. Lab (40%): You will work on design projects to implement knowledge learned from the lectures/lab, NEC code, and previous courses. Some Assignments will include “SKM Power Tools” software. Some assignments will be given and due during the same lab session. Always bring/have Reference #2 and #3 ready for use. Homework/lab Format: Use engineering graph paper. Write with good penmanship. This does not have to be all caps; it can just be clean, legible print writing. Write on the grid lines. Use a straight edge to draw diagrams. Organization is important. Refrain from cramming information in tiny spaces. Use plenty of paper; this communicates your work more efficiently. Show your work. Communicate enough information so someone can pick up your paper and know what you solved for and how you solved the problem. Box all of your answers. If submitting via Canvas, the submission requirements are: File Format: Submit Each homework/lab assignment as a single file in a PDF format (Scan using a scanner or phone application). The PDF file must be clear and legible. File Name: Student Name followed by the Assignment number, e.g.: Moe_Alahmad_HW#1 File Size: The maximum size accepted by Canvas is 5 GB. Exams (30%): Two Exams may be substituted for special assignments and given as a take-home. Exam #1 (15%) Thursday, March 7, 2024, 1:30-2:45 (if in class) Exam #2 (Final Exam) (15%) Thursday, May 16, 2024, 12:30 - 2:30 PM (if in class) Note: Exam #2 may be substituted for a particular class project; more information will be provided during the lectures. Course Specifics: Promptness is essential in your college career but even more so in your future professional career. It is necessary to discipline yourself now for your future. Class and Lab lecture times start at designated times per the course schedule. All students are to be seated in the Class and the Lab and attentive at the start of each class/Lab—plan to be early. Attendance is mandatory and expected to be the same in this course as in your professional office. Lab attendance and participation are required. If you miss two Lab sessions, you will fail the course. Passing Grade in the Course: • Passing grades in the Homework and Exams portion of the class AND • Passing grade in the Lab portion of the class, AND • Attending every lab session (you may miss one Lab session only) 2 MAA, 1-23-2024 No electronics are allowed during the lecture (cell phones, iPads, laptops, etc...) unless used for class purposes.
