construct new FIR with given taps. | |

float | filter (float input) |
compute a single output value. | |
float | filter (const float input[], unsigned long dec) |
compute a single output value; designed for decimating filters. | |
void | filterN (float output[], const float input[], unsigned long n) |
compute an array of N output values. | |
void | filterNdec (float output[], const float input[], unsigned long n, unsigned long decimate) |
compute an array of N output values, decimating the input | |
unsigned int | ntaps () const |
void | set_taps (const std::vector< float > &taps) |

FIR with internal buffer for float input, float output and float taps.
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.

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
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.
