Abstract
EL DISPOSITIVO SIRVE PARA EL REGISTRO AL MISMO TIEMPO DE DOS OSCILACIONES ELECTRICAS CON DIFERENTES FRECUENCIAS. SE HA PREVISTO PARA ELLO DE UN CUARZO (1) OSCILANTE CON AL MENOS DOS FRECUENCIAS DE RESONANCIA DIFERENTES. UN EMISOR DE UN PRIMER TRANSISTOR (2) ESTA UNIDO POR MEDIO DEL CUARZO OSCILANTE CON UN EMISOR DE UN SEGUNDO TRANSISTOR (9). LAS BASES DE LOS TRANSISTORES ESTAN UNIDAS RESPECTIVAMENTE POR MEDIO DE UN CIRCUITO (11,17) DE OSCILACION BASICA CON UN POTENCIAL DE REFERENCIA INFERIOR Y LOS COLECTORES DE LOS TRANSISTORES (3) ESTAN UNIDOS DE FORMA RESPECTIVA POR MEDIO DE UN CIRCUITO (5,14) DE OSCILACION DE COLECTOR CON UN POTENCIAL DE REFERENCIA SUPERIOR. LA BASE RESPECTIVA DE UNO DE LOS TRANSISTORES ESTA UNIDA ELECTRICAMENTE CON EL COLECTOR RESPECTIVO DEL OTRO TRANSISTOR. LAS BASES DE LOS TRANSISTORES ESTAN CONEXIONADAS RESPECTIVAMENTE POR MEDIO DE UN ACOPLADOR DE CORRIENTE ALTERNA AL POTENCIAL DE REFERENCIA INFERIOR.
