ECE 30100 - Signals and Systems

Lecture Hours: 3 Credits: 3

Professional Attributes
CMPE Core
EE Core

Normally Offered: Each Fall, Spring, Summer

Requisites:
(ECE 20200, Minimum Grade of C or BME 30500) and (MA 26200 or MA 36600 or MA 26600).

Catalog Description:
Classification, analysis and design of systems in both the time- and frequency-domains. Continuous-time linear systems: Fourier Series, Fourier Transform, bilateral Laplace Transform. Discrete-time linear systems: difference equations, Discrete-Time Fourier Transform, bilateral z-Transform. Sampling, quantization, and discrete-time processing of continuous-time signals. Discrete-time nonlinear systems: median-type filters, threshold decomposition. System design examples such as the compact disc player and AM radio.

Course Objectives:
To develop the analytical tools and techniques needed for the design and analysis of discrete-time and continuous-time linear systems - convolution, transforms, and sampling theory are therefore the primary topics.

Required Text(s):
  1. Signals and Systems, 2nd Edition, Oppenheim, Willsky, and Hamid, Prentice-Hall, 1996, ISBN No. 9780138147570.
Recommended Text(s):

Learning Objectives:

A student who successfully fulfills the course requirements will have demonstrated:
  1. an ability to classify signals (e.g. periodic, even) and systems (e.g. causal, linear) and an understanding of the difference between discrete and continuous time signals and systems. [a]
  2. an ability to determine the impulse response of a differential or difference equation. [a]
  3. an ability to determine the response of linear systems to any input signal by convolution in the time domain. [a,e,k]
  4. an understanding of the definitions and basic properties ( e.g. time-shift, modulation, Parseval's Theorem) of Fourier series, Fourier transforms, bilateral Laplace transforms, Z transforms, and discrete time Fourier transforms and an ability to compute the transforms and inverse transforms of basic examples using methods such as partial fraction expansions. [a]
  5. an ability to determine the response of linear systems to any input signal by transformation to the frequency domain, multiplication, and inverse transformation to the time domain. [a,e,k]
  6. an ability to apply the Sampling theorem, reconstruction, aliasing, and Nyquist's theorem to represent continuous-time signals in discrete time so that they can be processed by digital computers. [a,e,k]
Assessment Method for Learning Objectives: none
