The following page provides some supplemental information for the RC Circuits and Filtering lab for EGR 224L. It has been updated for Spring, 2018.
Clarifications
- If any of your figures looks wrong, it probably is! Be sure to have a TA check your figures so that you leave the lab with a valid data set.
- Use MATLAB on the PC to do the data acquisition
- For newer versions of MATLAB (2015 and after), the proper way to get out of a "keyboard" environment is to type the word "dbcont" and hit enter; the word "return" no longer works for that
- For Maple, when you put in the sinusoid at 60 rad/s, Maple may try to be "helpful" and use double angle formula to come up with a result that is a complete mess; try a frequency of 60.01 rad/s instead. It's just about the same speed and Maple won't be...helpful...
