FIR< T > Class Template Reference

Finite Impulse Response (FIR) filter. Performs convolution of the input signal with a set of feedforward coefficients b[]. For integer types, an optional scaling factor is applied to preserve precision. You can use https://www.arc.id.au/FilterDesign.html to design the coefficients. More...

needs_divide()

template<typename T = float>

needs_divide ( factor !  = T(1) )

inline

process()

template<typename T = float>

T process ( T  in )

inlineoverridevirtual

Processes the input value and returns the filtered output value.

Implements Filter< T >.

reset()

template<typename T = float>

void reset ( )

inlineoverridevirtual

Clears the internal state (delay lines) without changing the coefficients. Call after reconfiguring filter parameters via begin() to avoid transients from stale state.

Reimplemented from Filter< T >.

setValues()

template<typename T = float>

template<size_t B>

void setValues ( const T(&)  b[B] )
