4.1RPM Filters - Analysis

Now it's getting interesting, let's do our first analysis.

Your job is pretty easy:

  1. Upload your saved logfile (btfl_all.bbl) into the analyzer below
  2. Count the Diagonal "lines" (harmonics) in your plot (see attached picture for reference) and remember that number (or write it down somewhere)
  3. Now you need to find the lowest frequency at which any of these lines start (the most left point of any of these lines) and also remeber that one / write it down
