Chapter 1: Introduction and Basic Signals and Systems

1. 1.2 Basic Definitions

   • A signal x(t) is a set of data or a function of time that represents a variable of interest
   • A system is a collection of devices that operate on an input signal x(t) [excitation] to produce an output signal y(t) [response]

2. 1.3 Classification of Signals

   • continuous-time signal: takes a value at every instant of time t
   • discreet-time signal: defined only at particular instants of time

3. 1.4 Basic Continuous Time Signals

4. 1.5 Basic Discreet Time Signals

5. 1.6 Basic Operations on Signals

6. 1.7 Classifications of Systems
