zpch1

Chebyshev analog filter

Syntax

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

Arguments

n

integer (filter order)

epsilon

real : ripple in the pass band (0<epsilon<1)

omegac

real : cut-off angular frequency in radians per second

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')

Examples

n = 13;
epsilon = 0.2;
omegac = 3;
[p,gain] = zpch1(n,epsilon,omegac)
