zpbutt
Butterworth analog filter
Calling Sequence
[pols,gain]=zpbutt(n,omegac)
Arguments
- n
integer (filter order)
- omegac
real (cut-off frequency in Hertz)
- 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'))
