(FR) CODAGE ET DÉCODAGE D'INFORMATIONS
Abstract
(EN) Method and system for weighting the amplitude of an event in a time -based code. The time-based code is divided into time intervals. Each of the time intervals of the time-based code corresponds to a digit in the received signal. Each digit of a first state of the received signal is expressed as a event occurring at a first time within the corresponding time interval of the time -based code. Each digit of a second state of the received signal is expressed as a event occurring at a second time within the corresponding time intervals of the time -based code, the first time is distinguishable from the second time. All of the states of the digits in the received signal are represented by events in the time-based code. The weighting is performed as a function of the timing of other events in the time-based code signal.
(FR) La présente invention porte sur des procédés, sur des systèmes et sur un appareil comprenant des programmes informatiques codés sur un support d'enregistrement informatique, pour le codage et le décodage d'informations. Selon un aspect de l'invention, les procédés de codage d'informations dans un codeur comprennent les actions qui consistent à recevoir un signal représentant des informations en utilisant un ensemble de caractères numériques discrets, à transformer, par un codeur, le signal reçu en un code temporel, et à émettre le code temporel. Le code temporel est divisé en intervalles de temps. Chaque intervalle de temps du code temporel correspond à un caractère numérique dans le signal reçu. Chaque caractère numérique d'un premier état du signal reçu est exprimé comme étant un évènement ayant lieu à un premier instant dans l'intervalle de temps correspondant du code temporel. Chaque caractère numérique d'un second état du signal reçu est exprimé comme étant un évènement ayant lieu à un second instant dans les intervalles de temps correspondant du code temporel, le premier instant pouvant être distingué du second instant. Tous les états des caractères numériques dans le signal reçu sont représentés par des évènements dans le code temporel.
