EGR 119/RC Lab

From PrattWiki

The following page provides some supplemental information for the RC Circuits and Filtering lab for EGR 119L. It has been updated to Spring, 2011.

Clarifications

• The first printing of the lab manual had a mistake on Page 6 - the code for "squeezing" the data, as given at the bottom of the page, should be:

Omega = logspace(log10(1), log10(3000), 100);
[HMag, HPhase, HOmega] = bode(H, Omega);
HMag   = squeeze(HMag);
HPhase = squeeze(HPhase);

Element Values

• Resistances:
  • 1, 2, 3, 13, 14, 15: 1 kΩ
  • 4, 5, 6: 2.2 kΩ
  • 7, 8, 9: 4.7 kΩ
  • 10, 11: 10 kΩ
  • 12: 15 kΩ
• Capacitances
  • 7, 10, 12: 1 μF
  • 4, 8, 11: 2.2 μF
  • 1, 5, 9, 13: 4.7 μF
  • 2, 6, 14: 10 μF
