• Here is a link to the lab sheet that you used in lab.  You should have submitted this before you left the lab.

        In the lab you built a filter that was a "low-pass" filter.  It should have filtered out high frequency signals and passed low frequency signals.  You used that filter to process an audio signal, and you should have heard a difference between the signals before filtering and after filtering.  Here is the question for you to answer.

• Explain what went on in lab.  The filter should either have reduced the bass in the signal or the treble.  You need to give a short explanation of what that implies for the music signal(s) that you listened to.  If, for example, the bass was removed what does that say about the signal?  (And, you may need to think about this question and bring your questions to class.)
