Class expression_short_fir¶

`class` expression_short_fir<tapcount, T, U, E1, stateless> dsp ¶

template <size_t tapcount, typename T, typename U, typename E1, bool stateless = false>
struct expression_short_fir : expression_with_traits<E1> { … }

Template expression applying a short FIR filter (2..33 taps).

Template parameters
tapcount	Internal (padded) tap count.
T	Coefficient type.
U	Sample/value type (may be complex).
E1	Input expression type.
stateless	If `true` , the state is held by reference.
