Class moving_sum_state¶
class moving_sum_state<U, Tag> dsp¶
template <typename U, univector_tag Tag = tag_dynamic_vector>
struct moving_sum_state { … }State for a moving-sum (rectangular window) filter with a compile-time-sized delay line.
| U | Sample/value type. |
| Tag | univector_tag describing the storage kind (default dynamic). |
