Isn't this one of the things that Microchip's Filter Lab was supposed to be able
to do for you?

Subject: [EE:] RC filter calculations?


For some reason, I can't find (thru google) the formula for calculating the
best values of R's and C's in this circuit for a given cutoff frequency...

   >----`\/\/\,----o----`\/\/\,-----o------>
           R1      |       R2       |
                  ---              ---
               C1 ---           C2 ---
                   |                |
   >---------------o----------------o------>

Any of you have the formula?

Thanks,
-Neil.
