Abstract: A processor-executed computational method especially for use in cryptographic systems quickly determines a polynomial quotient under specific conditions. For a polynomial modulus f(x), a maximum degree for a polynomial i(x) to be reduced by this method is defined as the sum of the degree of f(x) and the difference d between the degrees of the two highest degree coefficients of f(x).

Abstract: The invention relates to an audio system and a method for the stereo enhancement of decoded stereo signals. When decoded stereo signals are stereo enhanced, artefacts can be unmasked and can thus become audible. The invention tries to achieve that a stereo enhancement for decoded stereo signals which is possible without restrictions and without artefacts from becoming audible. It is suggested that a frequency range of the stereo signal is defined in which artefacts might be unmasked due to the stereo enhancement. The boost which is applied to the first of a total of two mono signals of which the stereo signal is composed of (the first signal might be the S-signal in the mid/side representation) is determined by an artefact remover. This makes it possible to attenuate the first mono signal S within the above frequency range. As a net result, the first mono signal S is not boosted within this frequency range, such that artefacts are not unmasked.
