What have we accomplished?

Time and frequency analysis

Signal representation using basic signals (unit-step, impulse, ramp, exponentials)

Connect signals and systems

Develop theory that approximates behavior of most systems

Where do we go from here?

Signal classification

Symmetry, periodicity, energy/power for continuous-time signals
