Man Scilab

zpch1 Scilab Function

zpch1 - Chebyshev analog filter

Calling Sequence

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

Parameters

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')
