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...

Template Parameters

T	sample type (float, double, or integer types with a scaling factor)

Constructor & Destructor Documentation

FIR()

template<typename T >

template<size_t B>

FIR ( const T(&)  b[B], const T  factor = 1.0  )

inline

Member Function Documentation

process()

template<typename T >

T process ( T  in )

inlineoverridevirtual

Processes the input value and returns the filtered output value.

Implements Filter< T >.

reset()

template<typename T >

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 >

template<size_t B>

void setValues ( const T(&)  b[B] )

inline
