zpch2

Chebyshev analog filter

Syntax

[zeros,poles,gain]=zpch2(n,A,omegar)

Arguments

n

integer : filter order

A

real : attenuation in stop band (A>1)

omegar

real : cut-off angular frequency in radians per second

zeros

resulting filter zeros

poles

resulting filter poles

gain

Resulting filter gain

Description

Poles and zeros of a type 2 Chebyshev analog filter gain is the gain of the filter

H(s)=gain*poly(zeros,'s')/poly(poles,'s')

Examples

n=10;
A=1/0.2;
omegar=6;
[z,p,gain]=zpch2(n,A,omegar)
