Abstract

OSCILADOR CONDUCIDO POR TENSION CON UN CUARZO OSCILANTE DE CERAMICA. PARA ELIMINAR EL TITILEO DE LA IMAGEN EN LOS TLEVISORES CON SEGURIDAD, SE NECESITAN, POR EJEMPLO OSCILADORES MUY EXACTOS, DIRIGIDOS POR TENSION. TAL OSCILADORES MUESTRAN NO OBSTANTE, CUANDO SE REALIZAN COMO IC, VARIOS ENLACES, O SEA TERMINALES. DESEABLEMENTE QUE SEA SIEMPRE UN IC CON LOS MENORES ENLACES POSIBLES. PARA REDUCIR LA PORCION DE TERMINALES EN UN OSCILADOR DIRIGIDO POR TENSION SE CONDUCE LA TENSION DE SALIDA DEL CUARZO OSCILANTE, CERAMICA (1) A LA ENTRADA DE UN REGULADOR DE FASE (P) CON DOS RAMOS, CONECTADOS PARALELAMENTE. EN UN RAMO HAY UN AMPLIFICADOR (5) Y EN EL OTRO RAMO ESTAN UN PASO DE BAJA FRECUENCIA (6), UN AMPLIFICADOR REGULABLES (7) Y UN CONMUTADOR DIRIGIBLE (8), CUYA PRIMERA ENTRADA ESTA UNIDA CON LA SALIDA DEL AMPLIFICADOR REGULABLE (7), Y CUYA SEGUNDA ENTRADA ESTA SOBRE EL POTENCIAL DE REFERENCIA Y CUYA SALIDA ESTA UNIDA CON LA PRIMERA ENTRADA DE UN SUMADOR (9), CUYA SALIDA ESTA ACOPLADA REGENERATIVAMENTE SOBRE EL CUARZO OSCILANTE (1) DE CERAMICA (1).
