Detailed Description
Concrete class for generic implementation of FIR with float input, float output and float taps.
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)

Member Function Documentation
| virtual float gr_fir_fff_generic::filter | ( | const float | input[] | ) | [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.
Implements gr_fir_fff.
Reimplemented in gr_fir_fff_altivec, gr_fir_fff_armv7_a, and gr_fir_fff_simd.
| virtual void gr_fir_fff_generic::filterN | ( | float | output[], |
| const float | input[], | ||
| unsigned long | n | ||
| ) | [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.
Implements gr_fir_fff.
| virtual void gr_fir_fff_generic::filterNdec | ( | float | output[], |
| const float | input[], | ||
| unsigned long | n, | ||
| unsigned | decimate | ||
| ) | [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.
Implements gr_fir_fff.
