Each lecture is available in two separate formats: as a "Producer" file and as a "Breeze" file. The Producer lectures have video along with the powerpoint slides, but the Breeze lectures only have the audio. The Breeze lectures, of course, are viewable with a lower-speed connection. Both file formats have an outline for each lecture (which is just the titles of the powerpoint slides) and allow you to jump to any slide in the lecture. You may, however, occasionally experience problems with the synchronization between the audio/video and the slides if you jump from slide to slide (at least in the Producer lectures). If you think the items showing up on the slide are behind the video you can try clicking in the powerpoint frame with your mouse - the slide should advance one element for each click.
For the Producer lectures that give you a choice, we recommend selecting the 300Kbps setting. The quality is just as good as the 800Kbps and they run more smoothly. All of the lectures are also available as pdf files so that you can follow along and take notes as you listen.
If you experience technical difficulties with any of these lectures, please email Professor Spencer at spencer@ece.ucdavis.edu.
| Lecture | Description |
| 1 | 43 minutes: Covers basic op amp operation, negative
feedback & virtual short circuit, gain circuits,
frequency-dependent circuits (LPFs and HPFs used as
differentiators and integrators), offsets, slew rate and
full-power bandwidth.
Slides in pdf format. |
| 2 | 36 minutes: Covers power conditioning, DC-to-DC
conversion, switching regulators and linear regulators.
Slides in pdf format. |
| 3 | 50 minutes: Covers pulse-width modulation (PWM), a
comparator with hysteresis, relaxation oscillators, the
555 timer, review of basic electromagnetics, magnetic
sensing, DC motor operation & modeling.
Slides in pdf format. |
| 4 | 42 minutes: Covers DC motor speed control and track
sensing.
Slides in pdf format. |
| 5 | 48 minutes: Covers negative feedback as a control
loop, stability (including loop gain and phase, Nyquist
plots and gain and phase margins), step responses,
root-locus plots.
Slides in pdf format. |
| 6 | 53 minutes: Covers proportional, integral and
derivative (PID) controllers, a kinematic model of the
car, simulated response, and compensation of the
steering control loop. I have removed this lecture because the material changed significantly. You can get the slides used for the 2008 lecture from the schedule page. |
| 7 | 40 minutes: Covers microprocessor-based
considerations, Adapt9S12E128 processor board overview,
digital I/O on the Adapt9S12E128, A-to-D conversion on
the Adapt9S12E128.
Slides in pdf format. |
| 8 | 40 minutes: Covers configuring the clocks on the
Adapt9S12E128 and an overview of interrupts on the
Adapt9S12E128.
Slides in pdf format. |
| 9 | Not used. |
| 10 | 71 minutes: Covers reliability and manufacturability;
causes of system failure and design for reliability (DFR)
procedures. NOTE: The video of the Tacoma Narrows bridge collapse does work in the Breeze presentation, it does not in the Producer presentation.
Slides in pdf format.
Note: these were modified slightly in 2007, as was this
lecture, so these notes are the newer ones. |
| 11 | 41 minutes: Covers practical design and construction
information, testing, debugging, safety, cost, task
scheduling and report writing.
