Resonator class

---

Additional functions inherited from Filter.

Resonator(sampleType aFrequency = 0.0, sampleType aBandwidth = 100.0);

Sets all internal delays to zero. setHzForm(), and setBandwitdhForm() functions called.

Resonator~();

Does nothing.

void action(void);

calculates the next sample of the resonator.

sampleType getBandwidth(void);

Returns the bandwidth of the resonator in units of Hertz.

sampleType getFrequency(void);

Returns the resonance frequency of the resonator.

sampleType getOmega(void);

Returns the normalized angular frequency of the pole on the z-plane.

sampleType getPoleRadius(void);

Returns the radius of the pole on the z-plane.

sampleType output(int index);

Returns the current output.

void setBandwidth(sampleType aBandwidth);

Sets the bandwidth of the resonator in units of Hertz. If a signal is connected to input channel 2, then this bandwidth value is ignored.

void setBandwidthForm(void);

If an input is connected to input channel 2, then it is interpreted as a Bandwidth of the resonator in units of Hertz. Reverses the effect of setRadiusForm.

void setFrequency(sampleType aFrequency);

Sets the resonance frequency of the Resonator object in units of Hertz. If a signal is connected to input channel 2, then this frequency value is ignored.

void setHzForm(void);

If an input is connected to input channel 1, then it is interpreted as resonance frequency in units of Hertz. Reverses the effect of setOmegaForm.

void setOmega(sampleType anOmega);

Sets the angle of the pole in the z-plane. Unis are that of a normalized angular frequency (0 = 0 Pi, 1 = 1 Pi, etc.).

void setOmegaForm(void);

If an input is connected to input channel 1, then it is interpreted as an angle of the pole of the resonator on the z-plane. Reverses the effect of setHzForm.

void setPoleRadius(sampleType aPoleRadius);

Sets the radius of the pole in the z-plane. If input channel 2 is connected to a signal, then this radius value is ignored.

void setRadiusForm(void);

If an input is connected to input channel 2, then it is interpreted as a radius of the pole of the resonator on the z-plane. Reverses the effect of setBandwidthForm.
