Detailed Description
FIR with internal buffer for float input, gr_complex output and gr_complex taps.
Constructor & Destructor Documentation
gri_fir_filter_with_buffer_fcc::gri_fir_filter_with_buffer_fcc |
( |
const std::vector< gr_complex > & |
taps | ) |
|
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
gr_complex gri_fir_filter_with_buffer_fcc::filter |
( |
float |
input | ) |
|
compute a single output value.
input
is a single input value of the filter type
- Returns:
- the filtered input value.
gr_complex gri_fir_filter_with_buffer_fcc::filter |
( |
const float |
input[], |
|
|
unsigned long |
dec |
|
) |
| |
compute a single output value; designed for decimating filters.
input
is a single input value of the filter type. The value of dec is the decimating value of the filter, so input[] must have dec valid values. The filter pushes dec number of items onto the circ. buffer before computing a single output.
- Returns:
- the filtered input value.
void gri_fir_filter_with_buffer_fcc::filterN |
( |
gr_complex |
output[], |
|
|
const float |
input[], |
|
|
unsigned long |
n |
|
) |
| |
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.
void gri_fir_filter_with_buffer_fcc::filterNdec |
( |
gr_complex |
output[], |
|
|
const float |
input[], |
|
|
unsigned long |
n, |
|
|
unsigned long |
decimate |
|
) |
| |
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.

- Returns:
- number of taps in filter.
void gri_fir_filter_with_buffer_fcc::set_taps |
( |
const std::vector< gr_complex > & |
taps | ) |
|
install new_taps
as the current taps.
