  1. Please read Chapter 1 in the Kamen/Heck as follows: read section 1.1, browse sections 1.2-1.4, and read section 1.5. The key concepts are: what is a signal, what is a system, continuous-time versus discrete-time, and what does it mean for a system to be linear, time-invariant, and causal.

  2. Obtain Bode plots (magnitude and phase versus frequency) for the following circuits. What kind of filter is each circuit? How does the cutoff frequency depend on the values of R and C? On your plots, be sure to label the pass-band gain, the cutoff frequency, and the slope of the roll-off in the stop-band.
