buttmag
Power transmission of a Butterworth filter
Syntax
[h]=buttmag(order,omegac,sample)
Arguments
- order
integer : filter order
- omegac
real : cut-off angular frequency (in rad/s)
- sample
real vector of angular frequencies (in rad/s), where the transmission must be evaluated.
- h
Butterworth filter values at sample points
Description
squared magnitude response of a Butterworth filter
omegac
= cutoff frequency ; sample
= sample of frequencies
