Abstract

"SINAL RADIODIFUNDIDO POR DIFUSãO SIMULTâNEA DE AM, MéTODO PARA GERAR O MESMO, E, GERADOR DE SINAL RADIODIFUNDIDO POR DIFUSãO SIMULTâNEA DE AM". Um sinal radiodifundido por difusão simultânea de AM combinando um sinal de transmissão digital e um sinal de transmissão analógico em um canal de transmissão. O sinal de transmissão digital é modulado a uma banda lateral de uma portadora do canal de transmissão e um sinal de correção (C) é modulado à outra banda lateral da portadora do canal de transmissão, qual sinal de correção (C) é determinado de forma que a demodulação em envelope do canal de transmissão represente o sinal de transmissão analógico.
