**Exam 2**will be in-class on Wednesday, March 30. The exam will be closed-book and closed-notes, except that you can bring one page of 8.5 in. by 11 in. paper with notes and formulas, along with a calculator. The topics for the exam include the following. The material is in Chapters 2 and 3 of the Bobrow text, and in the notes that I distributed on sinusoids, phasors, and impedance. We worked with this material in homework assignments 4-9 and labs 4-8.- Nodal analysis of circuits
- Op amps: ideal model with negative feedback (3 zeros), applications (inverting, summing, D/A converter, buffer, etc.)
- Thevenin equivalent circuit model, maximum power transfer to a load
- Capacitors and inductors: current-voltage formulas, series and
parallel equivalents, differential equations and solutions for
closing/opening switches,
*time constant*. - Sinusoidal response of circuits: phasors, impedance, frequency response (Bode plot), frequency-selective filters (lowpass, highpass, bandpass, bandstop).

- Please make sure you have completed the Bode plots in Lab 8, including your measured data and the analytical formulas. The measured and analytical results should agree closely over most of the frequency range. I will look for these plots the next time that I grade your lab notebooks (probably at the end of the semester).
- In lab this week, we will work on a digital stopwatch in Lab 9, using the documentation in the materials distributed in class. Matt Sharp will run this lab session.
- For the week of April 4, please read Sections 11.1-11.4 on digital logic in the Bobrow text.
