1. Chapter 1: Overview of Signals and Systems

2. Signals Can be measured –Voltages –Currents –Tempertures –Pressures –Images –etc

3. Systems Hardware that processes signals Control –Car with cruise control system Signal Processing –CD, CD player, etc Communications –Radio waves, superheterodyne receiver, speakers, etc

4. Ch. 2 Continuous-time Signals A signal is a function of an independent variable such as –Time –Location –Angle Signals can be measured Definition vs description vs property

5. Function Algebra Sum of functions Product of functions Quotient of functions Difference of functions Point-by-point operation Composition of functions (functions of functions)

6. Basic C-T signals Unit step function Unit Impulse function –Product with unit impulse function (sifting property = equivalence property) –Relationship to unit step –Use in integrals

7. Basic C-T signals Exponential signals Sinusoidal signals –Angular measurments,
