Function Documentation

GR_CORE_API gr_freq_xlating_fir_filter_scc_sptr gr_make_freq_xlating_fir_filter_scc ( int  decimation,
const std::vector< gr_complex > &  taps,
double  center_freq,
double  sampling_freq 

Construct a FIR filter with the given taps and a composite frequency translation that shifts center_freq down to zero Hz. The frequency translation logically comes before the filtering operation.
