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')
