Abstract

"GERADOR DE SINAL DE DIFUSãO SIMULTâNEA DE PICO REDUZIDO PARA UM SINAL RADIODIFUNDIDO DIGITAL E UM SINAL RADIODIFUNDIDO ANáLOGO, MéTODO PARA GERAR O DITO SINAL, SINAL RADIODIFUNDIDO DE DIFUSãO SIMULTâNEA, E, PRODUTO DE PROGRAMA DE COMPUTADOR". Um gerador de sinal de difusão simultânea de pico reduzido e um método para gerar um sinal de difusão simultânea atenuado em pico estável, que combina um sinal radiodifundido digital e um sinal radiodifundido análogo, são descritos. O gerador de sinal de difusão simultânea inclui pelo menos um estágio de atenuação para atenuar o sinal radiodifundido digital e/ou análogo a fim de obter um sinal de difusão simultânea estável. Cada estágio de atenuação inclui um gerador de sinal de difusão simultânea para gerar um sinal de erro, e meio de atenuação que atenua, em dependência do dito primeiro sinal de erro, pelo menos um do sinal radiodifundido análogo e do digital.
