Abstract

"APARELHO PARA A MONITORAçãO DE UMA REDE, MéTODO PARA A MONITORAçãO DE UMA REDE E MEIO QUE PODE SER LIDO EM COMPUTADOR". A presença de microrreflexões é determinada em uma rede pela determinação de microrreflexões a partir de não combinações de impedância de amplificador e filtro diplexador e microrreflexões a partir de não combinações de impedância de cabo de transmissão. As microrreflexões de não combinações de impedância são determinadas pela instrução de um elemento de rede para transmitir um sinal de teste a uma primeira taxa de símbolo e uma primeira resolução para não combinações de impedância de amplificador e filtro diplexador e uma segunda freqüência com uma segunda taxa de símbolo e uma segunda resolução para microrreflexões de não combinações de impedância de cabo de transmissão. Os testes são realizados com várias freqüências e os canais com o mínimo de microrreflexões identificados.
