Abstract
"PROCESSO PARA RETRANSMITIR SINAIS DE FREQENCIA INDIVIDUAIS E UM REPETIDOR DE SINAL DE FREQUêNCIA INDIVIDUAL". A invenção apresenta um processo para a retransmissão de sinais de freq³ência individuais e um repetidor de sinal de freq³ência individual onde ocorre o acoplamento entre a antena de transmissão e a antena de recepção, e onde o processo é do tipo usado em um repetidor de sinal de freq³ência individual e compreende as etapas de: [a] receber um primeiro sinal de freq³ência de rádio tendo uma potência de recepção particular, [b] converter, opcionalmente, tal primeiro sinal de freq³ência de rádio em um sinal de processo, [d] filtrar, ampliar e controlar, automaticamente, o ganho de tal sinal, [d] cancelar tal acoplamento entre tal antena de transmissão e tal antena de recepção, [e] reconverter, como pode ser o caso, tal sinal de processo em um segundo sinal de freq³ência de rádio, [f] ampliar a potência de tal segundo sinal de freq³ência de rádio, [g], providenciar a filtração de saída e [g]a transmissão.
