Member Function Documentation

void gr_pfb_synthesis_filterbank_ccf::print_taps ( )

Print all of the filterbank taps to screen.

void gr_pfb_synthesis_filterbank_ccf::set_taps ( const std::vector< float > &  taps)

Resets the filterbank's filter taps with the new prototype filter

Parameters
taps(vector/list of floats) The prototype filter to populate the filterbank.
