Course Structure: The class meets for four lectures a week, each consisting of two 50-minute sessions. 4-5 Matlab homework assignments are given per semester.  There are two in-class mid-term exams and a final exam.  In addition 5-7 unannounced quizzes are given to check the awareness of the students. 

Laboratory Resources: None.

 

Grading:

 

1.     Matlab homework sets (15%)

2.     Two mid-term exams (23% each).

3.     Final exam (24%)

4.     Quizzes (15%).

 

Outcome Coverage:

 

(a)   Apply math, science and engineering knowledge.  This course requires working knowledge of signal processes, transform theory, spectral analysis and an engineering intuition to grasp the meaning of information transport processes. 

(b)   Design a system, component or process to meet desired needs. A few examples of system design shown in the class.  

(c)   Use of modern engineering tools. Students are encouraged to use Matlab simulation tools for describing and analyzing signals and modulations.
