Detailed Description

template<class iType, class oType, class taptype>
class GrIIRfilter< iType, oType, taptype >

Member Function Documentation

template<class iType, class oType, class taptype> void GrIIRfilter< iType, oType, taptype >::initialize (   )  [virtual]

Initialize any local state that is dependent on sampling frequency. Reimplemented from VrSigProc.

template<class iType, class oType, class taptype> virtual const char* GrIIRfilter< iType, oType, taptype >::name (   )  [inline, virtual]

default name for a module (override with actual name) Reimplemented from VrSigProc.

template<class iType, class oType, class taptype> int GrIIRfilter< iType, oType, taptype >::work (  VrSampleRange  output, void *  o[], VrSampleRange  inputs[], void *  i[] )  [virtual]

Generate up to output.size output points at o[output#][sample#] using data at the inputptrs[input#][sample#]. Pointers start at corresponding VrSampleIndex in the range params. output.size is a multiple of outputSize. Returns the number of outputs (<= output.size) that it was able to compute with the given input ranges. If this value is < output.size, forecast() will need to be called again. Implements VrSigProc.
