Abstract
In order to transform an input digital signal (x) into one or more output digital signals (y) containing even-indexed samples (y) and odd-indexed samples (y), this filtering method includes at least one iteration which contains an operation of modifying even-indexed samples (y) by a function (R) of weighted odd-indexed samples (y), and an operation of modifying odd-indexed samples (y) by a function (R) of weighted even-indexed samples (β(y−y)). The weighted samples are obtained by at least one weighting operation. At least one of the weighting operations is applied to the difference between two consecutive even-indexed samples.
