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...

Processes the input value and returns the filtered output value.

Implemented in BiQuadDF1< float >, and BiQuadDF2< float >.

reset() [1/2]

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< float >.
