Detailed Description

Implementation of the Attenuator class for simulating an attenuator.

Author

Jan Benda

Version

1.1 The attenuation levels are stored in the global variable AttSimDecibel.

Constructor & Destructor Documentation

AttSim

(

void

)

Constructs an AttSim.

~AttSim

(

void

)

Close the attenuator simulation.

Member Function Documentation

int open ( const string &  device )

overridevirtual

Open the attenuator device driver specified by device.

Reimplemented from Attenuator.

References Attenuator::setInfo().

bool isOpen ( void  ) const

virtual

Returns true if the attenuator device driver was succesfully opened.

Implements Attenuator.

void close ( void  )

virtual

Close the attenuator device driver.

Implements Attenuator.

const Options & settings ( void  ) const

virtual

Returns the current settings of the attenuator.

References ConfigClass::addNumber(), ConfigClass::addText(), ConfigClass::clear(), AttSim::Decibel, and Attenuator::MuteAttenuationLevel.

int lines ( void  ) const

virtual

Returns the number of attenuator devices the driver handles.

Implements Attenuator.

References AttSim::MaxDevices.

double minLevel ( void  ) const

virtual

Returns the minimum possible attenuation level in decibel. This number can be negative, indicating amplification.

Implements Attenuator.

double maxLevel ( void  ) const

virtual

Returns the maximum possible attenuation level in decibel.

Implements Attenuator.

void levels ( vector< double > &  l ) const

virtual

Returns in l all possible attenuation levels sorted by increasing attenuation levels (highest last).

Implements Attenuator.

References relacs::ceil().

int attenuate ( int  di, double &  decibel  )

virtual

Set the attenuation level of the subdevice specified by its index di to decibel decibel. Returns the actually set level in decibel.

Implements Attenuator.

References AttSim::Decibel, relacs::floor(), AttSim::MaxDevices, Attenuator::MuteAttenuationLevel, Attenuator::Overflow, and Attenuator::Underflow.

int testAttenuate ( int  di, double &  decibel  )

virtual

Tests setting the attenuation level of the subdevice specified by its index di to decibel decibel. Returns the actually set level in decibel.

Implements Attenuator.

References relacs::floor(), AttSim::MaxDevices, Attenuator::MuteAttenuationLevel, Attenuator::Overflow, and Attenuator::Underflow.
