Course Description
This course describes signals mathematically and understand how to perform mathematical operations on signals, to classify signals as continuous-time vs. discrete time, periodic vs. non-periodic, energy vs. power signal, odd vs. even, and conjugate symmetric vs. anti-symmetric, to understand the notion of an impulse response, to perform the process of convolution between signals and to understand its implication for analysis of linear time-invariant systems, to understand the application of Fourier analysis to ideal filtering, and to develop basic problem-solving skills and to become familiar with formulating a mathematical problem from a general problem statement.
Course Objective
The objective of this course is that by the end of the semester, you will have demonstrated
an ability to classify signals and systems;
a knowledge of impulse response functions and convolution for linear systems;
a knowledge of Fourier series and periodic signals;
an understanding of Fourier transforms for linear time invariant systems and the basics of sampling and its applications;
a knowledge of discrete time signals systems and transforms.

Grading
| No. | Item | % | Explanations for the conditions |
|---|---|---|---|
| 1. | Computer Assignments | 10% | The computer assignments will assist students to understand what they learned in class, making the theoretical equations into a figurative concept. |
| 2. | Midterms | 40% | (20% each). There are two mid-term exams in this course. Each mid-term is for 90 minutes. The midterms are scheduled on – Midterm 1: March 31 in class. – Midterm 2: May 12 in class. Midterms are closed-book, closed-notes. No electronics, including calculators, cell phones, or smart watches are allowed. Midterms will be used to access demonstration of the learning objectives. Some formulas and tables may be provided. |
| 3. | Final Exam | 30% | The final exam will be on June 02. The final is closed-book, closed-notes. No electronics, including calculators, cell phones, or smart watches are allowed. The final is cumulative, and some formulas and tables may be provided. |
| 4. | Final Team Project | 20% | Form a team of three people. The purpose of the team project is to provide you with hands-on experience in analyzing signals and related to what we have learned in class. You are also encouraged to propose topics related to your research. However, everything you propose should be within the scope of this course. If you have doubts about your proposed project, feel free to send me an email. You have to use LaTeX template available on NTU COOL to submit your report. A gallery appreciation will be held in class on WEEK 16, June 09. |
