Course Learning Outcomes
1. Express the concepts of signals and systems and their different types which can be used in a wide
variety of disciplines in engineering and study properties such as causality, stability, linearity, and
time invariance etc.
2. Use linear systems tools, especially transform analysis and convolution, to analyze and predict the
behavior of linear systems.
3. Analyze continuous and discrete time signals and systems in the time/frequency-domain using
Fourier, Laplace and z-transforms.
4. Concepts of sampling, sampling theorem and modulation and Gain an appreciation for the
importance of linear systems analysis in communication systems.
