zpch2(1) Scilab Function 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')
