Abstract

Patente de Invenção: <B>"PROCESSO PARA A TRANSMISSãO DE INFORMAçõES BEM COMO UM SISTEMA ADEQUADO PARA O PROCESSO"<D>. é descrito um processo para transmissão de informações, ou seja um sistema correspondente, que é adequado especialmente para transmissão digital. No caso, ao menos será gerado um sinal de informações constituído de um canal de freq³ência de referência e ao menos de um canal de freq³ência de informação, sendo que o canal de freq³ência de referência e o canal de freq³ência de informação formam estados descontínuos para prover um padrão de bit. Com isto consegue-se viabilizar uma transmissão de sinal também por vários quilómetros, por exemplo em ambiente submarino. Também será descrito um sistema de avaliação adequado e correspondente.
