Abstract

"COMUNICAçãO ENTRE UM RECEPTOR-TRANSMISSOR E UM INTERROGADOR". A presente patente de invenção refere-se à comunicação entre um receptor-transmissor e um interrogador, mais particularmente a um receptor-transmissor e a um método de transmissão de um sinal de resposta de um receptor-transmissor onde, em um sistema de recepção-transmissão, um receptor-transmissor passivo e energizado por um sinal contínuo de onda (CW) de freq³ência de rádio (RF) de um interrogador, e dito interrogador transmite o sinal de ativação CWRF a uma certa freq³ência e um receptor-transmissor responde pela transmissão de um código modulado na mesma, ou em uma freq³ência diferente e o interrogador recebe o sinal e lê o código pela detecção do sinal recebido.
