zpbutt

Butterworth analog filter

Syntax

[pols,gain]=zpbutt(n,omegac)

Arguments

n

integer (filter order)

omegac

real (cut-off angular frequency in radians per second)

pols

resulting poles of filter

gain

resulting gain of filter

Description

computes the poles of a Butterworth analog filter of order n and cutoff frequency omegac transfer function H(s) is calculated by H(s)=gain/real(poly(pols,'s'))

Examples

n=7;
omegac=3;
[pols,gain]=zpbutt(n,omegac)
