3rd order Sallen-Key Low-pass Filter Design Tool
This page is a web calculator that design a 3rd order Sallen-Key low-pass filter. Use this utility to simulate the Transfer Function for filters at a given frequency, damping ratio ζ or values of R and C. The response of the filter is displayed on graphs, showing Bode diagram, Nyquist diagram, Impulse response and Step response.
