Reading:
Please read Chapter 1 in the Lathi text.
Also, read Chapter 2 on signals.
I suggest that you read Chapter 2 rather quickly the first
time, trying to get the main ideas without getting lost in the details.
For topics that you studied in ELEC 320 (Linear Systems and Signals),
you might review your notes and text from ELEC 320 to refresh your
memory.
Then you will be able to reread Chapter 2 several more times
as we study it in more detail.
