gr_freq_xlating_fir_filter_scc Class Reference
[Filters]
FIR filter combined with frequency translation with short input, gr_complex output and gr_complex tapsThis class efficiently combines a frequency translation (typically "down conversion") with a FIR filter (typically low-pass) and decimation. It is ideally suited for a "channel selection filter" and can be efficiently used to select and decimate a narrow band signal out of wide bandwidth input.

Detailed Description
FIR filter combined with frequency translation with short input, gr_complex output and gr_complex taps
This class efficiently combines a frequency translation (typically "down conversion") with a FIR filter (typically low-pass) and decimation. It is ideally suited for a "channel selection filter" and can be efficiently used to select and decimate a narrow band signal out of wide bandwidth input.
Uses a single input array to produce a single output array. Additional inputs and/or outputs are ignored.

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.
