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')
