[Discuss-gnuradio] phase accumulator in gr_frequency_modulator_fc

[fangming he]

 Hi, All,

I cannot understand why the phase accumulator should be limited to  [-16*pi,16*pi]. Please clarify it for me if you have some ideas on it.

The following is the code in this class:
 if (fabs (d_phase) > 16 * M_PI){
    double ii = trunc (d_phase / (2 * M_PI));
    d_phase = d_phase - (ii * 2 * M_PI);
  }
