Sallen-Key Filter Design Tool

This program will calculate resistor values for an active filter up to 10th order based on user specified filter type (HPF or LPF), response (Bessel or Butterworth), Gain, and Capacitance. Images of the minimized code and example output for a 5th-order Butterworth HPF are shown below.

 

Download includes .m file, coefficient tables as .txt, and .png images of generic filters used by the program.
