DIGITAL_API digital_pfb_clock_sync_fff_sptr digital_make_pfb_clock_sync_fff ( double  sps,
float  gain,
const std::vector< float > &  taps,
unsigned int  filter_size = 32,
float  init_phase = 0,
float  max_rate_deviation = 1.5,

Build the polyphase filterbank timing synchronizer.

sps(double) The number of samples per second in the incoming signal
gain(float) The alpha gain of the control loop; beta = (gain^2)/4 by default.
taps(vector<int>) The filter taps.
filter_size(uint) The number of filters in the filterbank (default = 32).
init_phase(float) The initial phase to look at, or which filter to start with (default = 0).
max_rate_deviation(float) Distance from 0 d_rate can get (default = 1.5).
osps(int) The number of output samples per symbol (default=1).
