Summary
Compute exact zeroes of Butterworth and Cheybshev type I filter.
Unit
IIRFilters
Declaration
Procedure ExactIirZeros(Order: integer; Wc: TSample; FilterType: TFilterType; Analog: boolean; z: TVec);
Description
The order defies the Order of the filter, WC is the bilinear warped center frequency of the stopband of a bandstop filter. FilterType defines, if the filter is lowpass, highpass, bandpass or bandstop, Analog specifies, if the filter is designed for the s-domain or for the z-domain. The result is placed in z.
