Name

zpch2 — Chebyshev analog filter

Calling Sequence

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

Parameters

n

integer : filter order

A

real : attenuation in stop band (A>1)

omegar

real : cut-off frequency in Hertz

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')
