**Signals and Systems**

In our daily life, we communicate with each other, what is the mean by which we convey the message to the next person? Answer is *Signal*. Therefore Signal is the collection of data that can be processed by a *system* to get useful information. This course introduces the fundamental principles of signals and systems. These concepts form the building blocks for other important courses like Digital Signal Processing, Communication System, Network Systems, and Control Systems etc
