zpch2

zpch2 — Chebyshev analog filter

Calling sequence

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

`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

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')
