Revision as of 17:03, 7 April 2009
The following page provides some supplemental information for the Active Filters lab for EGR 119L. It has been updated to Spring, 2009.
Points of Clarification
- 8.4.2 - be sure to complete the wiring in Tables 5.1-5.4 EXCEPT for the wires that go into DAC0OUT, DAC1OUT, and AOGND. Repeat - do NOT install the red wires for DAC0OUT, DAC1OUT, or AOGND. If you are using more than one red wire, you have done something wrong! Installing these wires will short out your audio source and you will not be able to get sufficient volume.
