Almost done. Your final project lab report is due at 5pm in your instructor's mailbox.

#### Comments about expectations for final report

This report should be written at the level of the previous lab
reports, but covering more material. I would advise you to think
about your previous lab reports and what kind of information was
included. The lab report should be self contained. Introductions and
conclusions are expected. Important formulas describing the behavior
of a circuit element should be given. A complete circuit diagram
(with actual component values) should be given and the functioning of
the elements explained. Some examples of the kinds of things that are
expected:

- If you have a frequency filter in your system, make a bode plot
of its response and compare to theory. Extract a 3dB frequency(s).
Is the gain in the passband what you predict? Are the 3dB
frequencies close to what you predict?
- If you have a 555 timer in your circuit, give equations
describing how to program its behavior, the expected behavior and the
measured behavior.
- If you have a differential amplifier in your circuit, how does
it work? Can you explain how it accomplishes voltage subtraction?
- If you have a summing amplifier, how does it work?
- If you have resonant bandpass filters, measure its transfer
function and plot it on a linear/linear scale. Can you then
summarize its properties in terms of a center frequency and Q?
- If you have transistor stages, can you predict the input and
output impedance and whether it is high enough or low enough to
matter?
- If you have an inverting amplifier stage, give a formula for the
predicted gain and the measured gain. Can you quickly estimate the
3dB bandwidth from the unity gain frequency of the op-amp and the
gain? Is this enough bandwidth for your purposes?
- Are there important combinations of R's and C's that determine
the frequency response of your system? Identify them and compare to
your expected signal frequencies.
