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')
