SignalUtils.NotchFilter Function

Design a notch filer.

Pascal
procedure NotchFilter(NotchFrequency: double; r: double; num: TVec; den: TVec; FS: double = 2); overload;

Design a notch filter and place the transfer function in Num (numerator) and Den (denominator). You can then use this transfer function to initialize an IIR filter with a call to IirInit. A notch filter will filter out the notch frequency. and r defines the attenuation and width of the transition band. Typical values for r are from 0.99 to 0.9999.
