Course Objectives

By the end of the course, students will be able to:

Define signal and system
Describe control system characteristics
Model biomedical systems in the time and frequency domain
Determine the response of a biomedical system given an input
Analyze biomedical systems for stability
Design control systems given system specifications
Use MATLAB to solve control systems problems

General Information

If you have questions during reading, solving homework problems, writing up assignments, studying for exams, etc., send me an email with the question. I will respond to all students, “A student asked the following question…” so you will not be identified. Office visits are also welcome.

Homework Guidelines

Homework is due by the beginning of class on the due date.

You will lose points if the grader cannot read or follow your work. Make it neat, organized, and legible.

Homework is assigned to help you practice applying the principles you learn in class. Upload pictures/electronic copies of your HW to Blackboard. Late homework will receive a maximum grade of 50%. After 24 hours, late HW will receive a grade of 0%.

Follow the homework guidelines to receive full credit.

Use the following file naming convention for files uploaded to Blackboard: [last name]-[first initial]-HW[number] (example: walker-g-HW5)

Grades

The grades in this course are calculated from homework, exams, and the final. The breakdown is:

Assessment	Percentage
Homework	10%
Exams	52.5%
Final	37.5%

Final grades will be assigned based on the following scale:

Percentage	Letter
[100, 93]	A
(93, 90]	A-
(90, 87]	B+
(87, 83]	B
(83, 80]	B-
(80, 77]	C+
(77, 73]	C
(73, 70]	C-
(70, 60]	D
(60, 0]	F

AI Use

I encourage you to use AI as a tool to learn the material, but do not use it to perform your work for you. I’ve assembled some tips on using AI for engineering work.

University of Mississippi Policies
