Chebyshev2FilterModel

Chebyshev2FilterModel[n]
creates a lowpass Chebyshev type 2 filter of order n.

Chebyshev2FilterModel[{n, _c}]
uses the cutoff frequency .

Chebyshev2FilterModel[{"type", spec}]
uses the full filter specification .

Chebyshev2FilterModel[{"type", spec}, var]
expresses the model in terms of the variable var.

Details Details

Chebyshev2FilterModel returns the filter as a TransferFunctionModel.
Chebyshev2FilterModel[n] uses machine precision to return a filter with attenuation of at frequency 1.
In Chebyshev2FilterModel[{"type", spec}], filter specification can be any of the following:

	{"Lowpass",{_p,_s},{a_p,a_s}}	lowpass filter specification
	{"Highpass",{_s,_p},{a_s,a_p}}	highpass filter specification
	{"Bandpass",{_s1,_p1,_p2,_s2},{a_s,a_p}}	bandpass filter specification
	{"Bandstop",{_p1,_s1,_s2,_p2},{a_p,a_s}}	bandstop filter specification

Frequency values should be given in an ascending order.
Values and are respectively absolute values of passband and stopband attenuations.
Given a gain fraction , the attenuation .
