| class | gr_freq_xlating_fir_filter_scf |
| FIR filter combined with frequency translation with short input, gr_complex output and float 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. More... | |

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.
