Abstract

Patente de Invenção: <B>"PROCEDIMENTO E DISPOSIçãO PARA A AVALIAçãO DA QUALIDADE DE TRANSMISSãO DE UM SINAL DE INFORMAçõES DIGITAL"<D>. é indicado um procedimento para a avaliação da qualidade de transmissão de um sinal de informações digital no qual, para cada bit transmitido pelo emissor, é estabelecida no receptor uma medida para a confiabilidade da sua verdadeira identificação e submetido a um filtro passa-baixa. Uma disposição (1) para a realização do procedimento é conectável a um equalizador (3) e abrange um filtro passa-baixa (5) o qual, através do nivelamento da medida de probabilidade, fornece um sinal representativo para a avaliação da qualidade de transmissão.Invention Patent: <B> "PROCEDURE AND PROVISION FOR THE EVALUATION OF THE TRANSMISSION QUALITY OF A DIGITAL INFORMATION SIGNAL" <D>. a procedure is indicated for the evaluation of the transmission quality of a digital information signal in which, for each bit transmitted by the sender, a measure is established in the receiver for the reliability of its true identification and submitted to a low-pass filter. An arrangement (1) for carrying out the procedure is connectable to an equalizer (3) and comprises a low-pass filter (5) which, by leveling the probability measure, provides a representative signal for the evaluation of the transmission quality .
