Abstract

A finite impulse response (FIR) digital filter has an assigned filter function with assigned filter coefficients, an input receiving input samples, another input receiving confidence information values, and an output. Each input sample value is associated to an input confidence value and the filter output depends on both the input samples and the input confidence values.
