RC Filter Characterization

This data set is characterizing an RC circuit I built in an electronics lab class for my physics degree at UNM.  The "response data" files have frequency in Hz in the first row and the amplitude (in unknown units) in the second.  The "Power vs. Frequency" data sets have frequency in Hz in the first row like the others, but power in unknown units in the second row.   The units don't matter since I am only interested in the percentage and the drop off rate.
