This course explains **signals and systems** representations/classifications and also describe the **time and frequency domain** analysis of continuous time signals with **Fourier series, Fourier transforms** and **Z transforms**.

Demonstrate an understanding of the fundamental properties of linear systems, by explaining the properties to others.

Develop input output relationship for linear shift invariant system and understand the convolution operator for continuous and discrete time system.

Understand the limitations of Fourier transform and need for Laplace transform and develop the ability to analyze the system in s- domain.
