Note homework due Jan 26 - see homework folder.
Exercises using complex numbers, in particular converting from Cartesian to polar form and 
Euler's formula.
Examples of time shifting, reversal, and scaling.
Periodic signals, having infinite energy but finite average power.
Exponential signals, real case (growth or decay), purely imaginary case (periodic, sinusoidal).
General complex exponential signals.
Some on the discrete-time case (just geometric sequences).
I asked to be emailed dates for the 1st midterm to avoid.
