Function Documentation

GR_CORE_API gr_freq_xlating_fir_filter_ccc_sptr gr_make_freq_xlating_fir_filter_ccc	(	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.
