FIR with internal buffer for float input, float output and float taps.
◆ fir_filter_with_buffer_fff() [1/3]
gr::filter::kernel::fir_filter_with_buffer_fff::fir_filter_with_buffer_fff |
( |
const std::vector< float > & |
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.

◆ filter() [1/2]
float gr::filter::kernel::fir_filter_with_buffer_fff::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.
◆ filter() [2/2]
float gr::filter::kernel::fir_filter_with_buffer_fff::filter |
( |
float |
input | ) |
|
compute a single output value.
input
is a single input value of the filter type
- Returns
- the filtered input value.
◆ filterN()
void gr::filter::kernel::fir_filter_with_buffer_fff::filterN |
( |
float |
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.
◆ filterNdec()
void gr::filter::kernel::fir_filter_with_buffer_fff::filterNdec |
( |
float |
output[], |
|
|
const float |
input[], |
|
|

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.
◆ ntaps()
unsigned int gr::filter::kernel::fir_filter_with_buffer_fff::ntaps |
( |
| ) |
const |
|
inline |
- Returns
- number of taps in filter.
◆ operator=() [1/2]
◆ operator=() [2/2]
◆ set_taps()
void gr::filter::kernel::fir_filter_with_buffer_fff::set_taps |
( |
const std::vector< float > & |
taps | ) |
|
install new_taps
as the current taps.
