I refer you to National Semiconductors web page, go find their app notes
(they have pdf app-notes from their web page, but I got a copy of the most
excellent Linear Applications Handbook" which BTW, includes and analog, true
RMS power meter) , AN-779 " A Basic Introduction to Filters - Active,
Passive, and Switched-Capacitor". The math involves equations (quadratics,
and factored terms for higher-orders) in S, or Laplace transforms rather
than derivatives & integrals. They have other relevant articles of Forier
Xform, et.

Ha ha ha, he he he, ho ho ho. Another unbiased, impartial scientist :-)
