Abstract

Patente de Invenção: <B>"REPETIDOR DIGITAL"<D>. Um método de usar um repetidor digital para receber e retransmitir sinais de freq³ência de rádio (RF). O método inclui converter para baixo um primeiro sinal de RF para um sinal de freq³ência intermediária (IF), converter o sinal IF em um sinal digital, processar o sinal digital com um processador de sinal digital, amplificar o sinal digital em um sinal amplificado usando o processador de sinal digital, converter o sinal amplificado em um sinal analógico. O método inclui ainda mais converter para cima o sinal analógico para um segundo sinal de RF adequado para transmissão de antena.
