Abstract
CIRCUITO DE ALIMENTACION DE SEÑALES DIGITALES. LAS SEÑALES DIGITALES GENERADAS (1) SON ENVIADAS A UNA DE LAS ENTRADAS (A) DE UNA PUERTA O-EXCLUSIVA (3), CUYA SEGUNDA ENTRADA (B) ESTA CONECTADA A UN GENERADOR DE FRECUENCIA (4). ESTE PROPORCIONA UNA SEÑAL DE SALIDA PERIODICA UNIPOLAR Y DE FRECUENCIA MAYOR QUE LA FRECUENCIA MAXIMA DE REPETICION DE LAS SEÑALES DIGITALES. EL ARROLLAMIENTO PRIMARIO (5) DE UN TRANSFORMADOR (6) ESTA CONECTADO, POR UN LADO, CON LA SALIDA DEL GENERADOR DE FRECUENCIA (4), Y POR OTRO LADO, CON LA SALIDA (C) DE LA PUERTA O-EXCLUSIVA (3). Y EL SECUNDARIO ESTA CONECTADO A DOS CONDUCTORES (R, D) DEL SISTEMA CONDUCTOR.
