Introduction to Electronics
News and announcements

Final exam: April 20, 2023, 09:0012:00, in STH216.
Same rules as for the midterm: one sheet of formulas (no complete solutions) is allowed, calculators.
The exam will cover all of the material in the course, with questions similar to
those seen in homework assignments and covered in the lab. Please note that a passing grade
(50% minimum) must be achieved on the final exam in order to pass the course.

The lab final is set for March 29, 2023, 14:0017:00, in H300. You will be given a circuit to assemble, and you will need to demonstrate that you can use your benchtop instruments to investigate and analyze its properties. A brief written submission (one page) will be submitted by 17:00. For example, the circuit could be an RC filter, and you would need to assemble it, perform a series of measurements and plot its transfer function, generating a Bode plot, and discuss it briefly.

Comments 
Homework 
20% 
Expect a homework assignment every week or so; full marks given for demonstrated effort. Late penalty is a sinking cap of 15%/day. 
Labs 
32% 
All labs must be completed, and all lab reports submitted. 
Midterm 
10% 
An inclass written test: problems similar to homework, full marks require correct answers. If public health disallows inperson tests, there will be no midterm, and the weights of other grading components will be adjusted proportionately. 
Final 
30% 
A written final: problems similar to homework, full marks require correct answers. 50% minimum to pass the course. If public health disallows inperson exams, the final will be conducted as an oral final via a videolink. 
8% 
A lab test: analysis of a "blackbox" (unknown) circuit.
