Detailed Description

ATSC FPLL (2nd Version).

Used as follows: float float A/D --> GrFIRfilterFFF ----> GrAtscFPLL ---->

We use GrFIRfilterFFF to bandpass filter the signal of interest.

This class accepts a single real input and produces a single real output

Member Function Documentation

void GrAtscFPLL::initialize  )  [virtual]
 

Initialize any local state that is dependent on sampling frequency.

Reimplemented from VrSigProc.

virtual const char* GrAtscFPLL::name  )  [inline, virtual]
 

default name for a module (override with actual name)

Reimplemented from VrSigProc.

void GrAtscFPLL::set_initial_phase double  phase  )  [inline]
 

void GrAtscFPLL::set_no_update bool  a_no_update  )  [inline]
 

int GrAtscFPLL::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.
