Frequency Problem
Problem Freq1P01

Name_____________________________

        You have a signal that has frequency components at 100Hz or less.  The signal is corrupted by a strong signal at 1000Hz.  You need to reduce the effect of the 1000Hz signal by a factor of 10.  The filter circuit below is proposed.

• You need to design a filter (in this case, specify a time constant for the filter) that will reduce the 1000 Hz signal by a factor of 10.
• When you put the entire signal into the filter, how much will the signal at 100Hz be affected?
