Exam Review (optional): Thursday October 18th, 1-1:50pm in G125 Exam Thursday October 25th 1-1:50pm in DUANE G140 Covers lectures and labs (except microcontrollers) You may bring handwritten notes covering one side of one 8-1/2 x 11 piece of paper and a calculator (no textbooks/lab manuals) Final Projects Written project proposal (25 pts) due on November 6th 4pm 1 to 2 pages: explain main idea and approach of project. (You must talk to your lab instructor to get pre-approval.) Progress Report (25pts) due December 4th 4pm. - 1-3 pages describing your progress so far. - Include the circuit diagrams for your project. - describe major problems if any (we may be able to help!) Oral Presentation (75pts) on December 13th, 9 am – 4 pm (There will be a sign-up sheet at the door in G230. Pick a slot!) Computer-based presentation (e.g. PowerPoint etc.) and demonstration of your circuit (show that it works.) Final Project Report (75 pts) due on December 14th, 4 pm. Types of Projects List of old projects on website - some of them do not meet the current class requirements if you do not add an analog component Avoid digital, high-voltage, or mechanical projects. This course is on analog, small signal electronics. You can work alone or in groups of two. Complexity of the project must be proportional to number of students in the group Avoid random googling! 1) You must have a detailed understanding how the circuit works. 2) You must be able to predict what happens if we modify it 3) Designing a circuit from scratch vs. a googled circuit will be considered during grading.
