Member Function Documentation

double gain ( void  ) const

inline

Returns the gain factor.

Referenced by DecibelAttenuate::setGain().

void setGain

(

double

gain

)

Set the gain factor to gain.

References DecibelAttenuate::gain().

Referenced by DecibelAttenuate::setGain().

double offset ( void  ) const

inline

Returns the offset.

Referenced by DecibelAttenuate::setOffset().

void setOffset

(

double

offset

)

Set the offset to offset.

References DecibelAttenuate::offset().

Referenced by DecibelAttenuate::setGain().

void setGain	(	double	gain,
		double	offset
	)

Set the gain factor to gain and the offset to offset.

References DecibelAttenuate::setGain(), and DecibelAttenuate::setOffset().

void setDeviceIdent ( const string &  ident )

virtual

Set the device and the config identifier string to ident.

References ConfigClass::setConfigIdent().

void notify ( void  )

virtual

Set the Gain and Offset variable if the config is changed.

void init ( void  )

virtual

Adds offset and gain to the info().

Reimplemented from Attenuate.

int decibel ( double  intensity, double  frequency, double &  db  ) const

protectedvirtual

Transform the requested intensity intensity for the carrier frequency frequency of the signal into db decibel which are used to set the attenuation level. If intensity is set to MuteIntensity, the attenuator is muted.

Implements Attenuate.

References Attenuate::MuteAttenuationLevel, and Attenuate::MuteIntensity.

void intensity ( double &  intens, double  frequency, double  decibel  ) const

protectedvirtual

Transform the attenuation level decibel for the carrier frequency frequency of the signal into the intensity intens. If decibel is set to MuteAttenuationLevel, then MuteIntensity is returned in intens. This is the inverse function of decibel().

Implements Attenuate.

References Attenuate::MuteAttenuationLevel, and Attenuate::MuteIntensity.
