Detailed Description
Abstract class for FIR with gr_complex input, gr_complex output and float taps
This is the abstract class for a Finite Impulse Response filter.
The trailing suffix has the form _IOT where I codes the input type, O codes the output type, and T codes the tap type. I,O,T are elements of the set 's' (short), 'f' (float), 'c' (gr_complex), 'i' (int)
Constructor & Destructor Documentation
| gr_fir_ccf::gr_fir_ccf | ( | ) | [inline] |
construct new FIR with given taps.
Note that taps must be in forward order, e.g., coefficient 0 is stored in new_taps[0], coefficient 1 is stored in new_taps[1], etc.

Member Function Documentation
| virtual gr_complex gr_fir_ccf::filter | ( | const gr_complex | input[] | ) | [pure virtual] |
compute a single output value.
input must have ntaps() valid entries. input[0] .. input[ntaps() - 1] are referenced to compute the output value.
- Returns:
- the filtered input value.
Implemented in gr_fir_ccf_generic, gr_fir_ccf_armv7_a, and gr_fir_ccf_simd.
| virtual void gr_fir_ccf::filterN | ( | gr_complex | output[], |
| const gr_complex | input[], | ||
| unsigned long | n | ||
| ) | [pure virtual] |
compute an array of N output values.
input must have (n - 1 + ntaps()) valid entries. input[0] .. input[n - 1 + ntaps() - 1] are referenced to compute the output values.
Implemented in gr_fir_ccf_generic.
| virtual void gr_fir_ccf::filterNdec | ( | gr_complex | output[], |
| const gr_complex | input[], | ||
| unsigned long | n, | ||
| unsigned | decimate | ||
| ) | [pure virtual] |
compute an array of N output values, decimating the input
input must have (decimate * (n - 1) + ntaps()) valid entries. input[0] .. input[decimate * (n - 1) + ntaps() - 1] are referenced to compute the output values.
Implemented in gr_fir_ccf_generic.
| virtual const std::vector<float> gr_fir_ccf::get_taps | ( | ) | const [inline, virtual] |
- Returns:
- current taps
References gr_reverse().
| unsigned gr_fir_ccf::ntaps | ( | ) | const [inline] |
- Returns:
- number of taps in filter.
| virtual void gr_fir_ccf::set_taps | ( | const std::vector< float > & | taps | ) | [inline, virtual] |
install new_taps as the current taps.
Reimplemented in gr_fir_ccf_armv7_a, and gr_fir_ccf_simd.
