Review
We now understand the why of:
5V v
R
L
C
Today, look at response of networks
to sinusoidal drive.
Sinusoids important because signals can be
represented as a sum of sinusoids. Response to
sinusoids of various frequencies -- aka frequency
response -- tells us a lot about the system

For motivation, consider our old friend,
the amplifier: V

Observe vo amplitude as the frequency of the
input vi changes. Notice it decreases with
frequency.
Also observe vo shift as frequency changes
(phase).
Need to study behavior of networks for
sinusoidal drive.
