Comments on homework, based on questions during office hours today:

- The answer to problem 27 is unusual - and perhaps a bit surprising. Don't be thrown off track if you get an unexpected answer. This is simply a fluke of the numbers chosen for the components - there is nothing profound in the strange result.
- To complete Problem 31, you should read the last page of the Thevenin equivalents lecture slides. It explains exactly how to choose RL for maximum power.
- Problem 32 is a bit confusing because I used the same component names in both the original circuit and the model. I have changed the resistor names in the original circuit. Hopefully, this reduces potential confusion. The name changes do not affect anything else -- you will use same methods and the same component values, and you will get the same answers.

- There will be no quiz on Monday. We can probably use a bit of a breather after the exam. Also, we want to have the maximum time available to talk amplifiers.
- Homework set F is on the web site.
- Try to read ahead a bit on the amplifier, feedback, and op-amp material to help prepare for the op amp lab for this week.
