zpch2(1)

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')
