Overload List

#SignatureDescription
1void LowpassToLowpass(TVec *z, TVec *p, double &k, double Freq);Frequency transformation from a lowpass to a lowpass filter in s-domain.
2void LowpassToLowpass(TMtx *a, TVec *b, TVec *c, double &D, double Freq);Transform a lowpass filter prototype in state space form to a lowpass filter.

Overload 1: void LowpassToLowpass(TVec *z, TVec *p, double &k, double Freq);

Frequency transformation from a lowpass to a lowpass filter in s-domain.

Remarks:

Transform a lowpass filter prototype in zero-pole form to a lowpass filter, where the new cutoff frequency is Freq. Assumed sampling frequency is 2. The transformation is defined as ([1], p. 258): s -> s/W_u

Wu - new cutoff frequency
