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_simd, gr_fir_fff_altivec, and gr_fir_fff_armv7_a.

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.
