inline

Member Function Documentation

reset()

template<typename T = float>

void rack::dsp::TRCFilter< T >::reset ( )

inline

setCutoff()

template<typename T = float>

void rack::dsp::TRCFilter< T >::setCutoff ( T r )

inline

Sets the cutoff angular frequency in radians.

setCutoffFreq()

template<typename T = float>

void rack::dsp::TRCFilter< T >::setCutoffFreq ( T f )

inline

Sets the cutoff frequency.

f is the ratio between the cutoff frequency and sample rate, i.e. f = f_c / f_s

lowpass()

template<typename T = float>

T rack::dsp::TRCFilter< T >::lowpass ( )

inline

highpass()

template<typename T = float>

T rack::dsp::TRCFilter< T >::highpass ( )
