# Butterworth filter matlab

This MATLAB function returns the transfer function coefficients of an nth-order lowpass digital Butterworth filter with normalized cutoff frequency Wn. This MATLAB function returns the lowest order, n, of the digital Butterworth filter with no more than Rp dB of passband ripple and at least Rs dB of attenuation in . This MATLAB function returns the poles and gain of an order n Butterworth analog lowpass filter prototype. This MATLAB function is a lowpass Butterworth filter with numerator and denominator coefficients b and a of orders n and m, respectively.
