Abstract

SISTEMA DETECTOR DE UNA SEÑAL FANTASMA DE TELEVISION. CONSTA DE UNA PUERTA (60) QUE SUMINISTRA LA SEÑAL DE VIDEO; DE UN DETECTOR DE COINCIDENCIA (74); DE UN SEPARADOR DE SINCRONISMO (72) CUYA SALIDA SE APLICA A UN CIRCUITO DE RAMPA (76) Y A UN CIRCUITO DE DISPARO (78) CONTROLADO POR TENSION; DE UN GENERADOR DE IMPULSOS (80) CUYA SALIDA ESTA ACOPLADA AL DETECTOR DE COINCIDENCIA (74); DE UN CIRCUITO DE CONTROL (82) CUYA SALIDA ESTA ACOPLADA A UN DETECTOR DE COINCIDENCIA (86) ADICIONAL, Y DE UN CIRCUITO DE CONMUTACION (88) PARA LA BUSQUEDA Y SEGUIMIENTO DE LA SEÑAL FANTASMA. CUANDO SE HA DETECTADO UNA SEÑAL FANTASMA, EL DETECTOR DE COINCIDENCIA (74) EMITE UNA SEÑAL INDICATIVA.
