zpch1

zpch1 — Chebyshev analog filter

Calling sequence

[poles,gain]=zpch1(n,epsilon,omegac)

`n`	: integer (filter order)
`epsilon`	: real : ripple in the pass band (`0<epsilon<1`)
`omegac`	: real : cut-off frequency in Hertz
`poles`	: resulting filter poles
`gain`	: resulting filter gain

Poles of a Type 1 Chebyshev analog filter. The transfer function is given by :



 H(s)=gain/poly(poles,'s')
