Abstract

"CODIFICAçãO DE NìVEIS MúLTIPLOS". Um sistema de conversão de níveis múltiplos para níveis múltiplos no qual um símbolo de nível N (0,1) é convertido em um nível N+1 (A, B, C), de tal modo que uma transição entre dois dos símbolos de saída de nível N+1 representa uma transição dos símbolos de entrada de nível N+1. O sistema de codificação de níveis múltiplos permite faixas aprimoradas de transferência de dados e proporciona auto-sincronização para a decodificação.
