zpch1(1)

NAME
zpch1 - Chebyshev analog filter

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

PARSMETERS

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

DESCRIPTION
Poles of a Type 1 Chebyshev analog filter. The transfer function is given by :
 H(s)=gain/poly(poles,'s')
