Class short_fir_state¶
class short_fir_state<tapcount, T, U> dsp¶
template <size_t tapcount, typename T, typename U = T>
struct short_fir_state { … }State for a short FIR filter (tap count in range 2..33).
| tapcount | Number of taps (rounded up to the next valid internal size). |
| T | Coefficient type. |
| U | Sample/value type (defaults to T). May differ from T, e.g. for complex-valued samples with real taps. |
function short_fir_state<tapcount, T, U>(const univector<T, N> &) ¶
template <size_t N>
short_fir_state(const univector<T, N>& taps)Construct from a runtime-sized tap vector.
| N | Size of the input tap vector. |
| taps | Filter coefficients (zero-padded to tapcount ). |

template <size_t N>
short_fir_state(const univector<const T, N>& taps)Construct from a runtime-sized tap vector (const data variant).
