Abstract

Patente de Invenção: <B>"CIRCUITO DE TRANSMISSãO DE DADOS COM UM TERMINAL EMISSOR E COM UM CIRCUITO DE RESPOSTA"<D>. A invenção refere-se a um circuito de transmissão de dados com um terminal emissor e com um circuito de resposta, onde o terminal de emissão apresenta uma bobina primária com um gerador de sinais para a geração de um campo alternado magnético com uma freq³ência portadora assim como um demodulador de amplitude, onde o circuito de resposta apresenta uma bobina secundária assim como um modulador de amplitude para atuar na carga da bobina secundária e onde o modulador de amplitude é desenvolvido de tal modo, que o campo alternado magnético é modulável com um sinal de dados. Sobretudo no caso de uma fabricação em massa do circuito de transmissão de dados ocorrem freq³entemente casos nos quais o sinal de dados modulado pelo circuito de resposta sobre o campo alternado magnético não é mais reconstruível no lado do terminal emissor. Constitui portanto tarefa da invenção oferecer um circuito de transmissão de acordo com o tipo apresentado, que funciona sempre de forma confiável. De acordo com a invenção o circuito de resposta apresenta um modulador de fase para atuar sobre as propriedades elétricas da bobina secundária, onde o modulador de amplitude e/ou o modulador de fase é desenvolvido de tal modo, que os mesmos sejam comandáveis por pelo menos um sinal de ativação.
