Member Function Documentation

void clIIRDecimator::Uninitialize (   )

Uninitialize decimator. Reimplemented from clIIRMultiRate. Definition at line 45 of file IIRDecimator.cc. References DecBuf, clAlloc::Free(), and clIIRMultiRate::Uninitialize(). Referenced by clRecDecimator::Uninitialize(), and ~clIIRDecimator().

void clIIRDecimator::Put (  const float *  , long  )

Feed data into decimator. Parameters: SrcData  Source data SrcCount  Source data count Definition at line 52 of file IIRDecimator.cc. References InBuf, and clReBuffer::Put(). Referenced by clRecDecimator::Put().

void clIIRDecimator::Put (  const double *  , long  )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Definition at line 58 of file IIRDecimator.cc. References InBuf, and clReBuffer::Put().

bool clIIRDecimator::Get (  float *  , long  )

Get data from decimator. Parameters: DestData  Destination buffer DestCount  Number of samples to fetch Returns: Success Definition at line 64 of file IIRDecimator.cc. References DecBuf, clDSPOp::Decimate(), DSP, clReBuffer::Get(), InBuf, clIIRMultiRate::lFactor, clIIRCascade::Process(), and clAlloc::Size(). Referenced by clRecDecimator::Put().

bool clIIRDecimator::Get (  double *  , long  )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Definition at line 79 of file IIRDecimator.cc. References DecBuf, clDSPOp::Decimate(), DSP, clReBuffer::Get(), InBuf, clIIRMultiRate::lFactor, clIIRCascade::Process(), and clAlloc::Size().
