◆ setup() [1/2]

template<int FilterOrder = 4, class StateType = DirectFormII>
void Iir::ChebyshevII::BandStop< FilterOrder, StateType >::setup ( double  sampleRate,
double  centerFrequency,
double  widthFrequency,
double  stopBandDb 
)
inline

Calculates the coefficients of the filter

Parameters
sampleRateSampling rate
centerFrequencyCenter frequency of the bandstop
widthFrequencyWidth of the bandstop
stopBandDbPermitted ripples in dB in the stopband

◆ setup() [2/2]

template<int FilterOrder = 4, class StateType = DirectFormII>
