Member Function Documentation

◆ setup() [1/2]

template<int FilterOrder = 4, class StateType = DirectFormII>
void Iir::Butterworth::HighPass< FilterOrder, StateType >::setup ( double sampleRate,
double cutoffFrequency )
inline

Calculates the coefficients with the filter order provided by the instantiation

Parameters
sampleRateSampling rate
cutoffFrequencyCutoff frequency

◆ setup() [2/2]

template<int FilterOrder = 4, class StateType = DirectFormII>
void Iir::Butterworth::HighPass< FilterOrder, StateType >::setup ( int reqOrder,
double sampleRate,
double cutoffFrequency )
inline

Calculates the coefficients

Parameters
reqOrderThe actual order which can be less than the instantiated one
sampleRateSampling rate
cutoffFrequencyCutoff frequency

◆ setupN() [1/2]

template<int FilterOrder = 4, class StateType = DirectFormII>
void Iir::Butterworth::HighPass< FilterOrder, StateType >::setupN ( double cutoffFrequency)
inline

Calculates the coefficients with the filter order provided by the instantiation

Parameters
cutoffFrequencyNormalised cutoff frequency (0..1/2)

◆ setupN() [2/2]

template<int FilterOrder = 4, class StateType = DirectFormII>
void Iir::Butterworth::HighPass< FilterOrder, StateType >::setupN ( int reqOrder,
double cutoffFrequency )
inline

Calculates the coefficients

Parameters
reqOrderThe actual order which can be less than the instantiated one
cutoffFrequencyNormalised cutoff frequency (0..1/2)
