Abstract

''PROCESSO PARA OPERAR UM RECEPTOR DE TELEVISãO DIGITAL, E, RECEPTOR DE TELEVISãO DE ALTA DEFINIçãO DIGITAL'' Um receptor de televisão digital inclui um filtro para minimizar a interferência NTSC com um sinal recebido tendo uma taxa de símbolos constante. Um equalizador tem dois retardos de um símbolo para cada derivação. Uma versão filtrada e não filtrada do sinal recebido são aplicadas a um multiplexador na entrada do equalizador, que é operada a duas vezes a taxa de símbolos. As saídas dos multiplexadores no equalizador são combinadas e aplicadas a um desmultiplexador. Os sinais equalizados filtrados e não-filtrados são comparados e uma seleção quanto a quais dos sinais recebidos filtrados e não filtrados deve ser processado é efetuada baseada sobre a comparação.
