Abstract
ES CONOCIDO GENERAR SEÑALES DE FORMA RECTANGULAR CON AYUDA DE UN SCHMITT-TRIGGERS (DETECTOR DE UMBRAL). ESTAS SEÑALES ESTAN PREVISTAS PARA LA SUPRESION DE INTERFERENCIAS DURANTE EL PASO POR CERO DE LA SEÑAL DE ENTRADA CON UNA HISTERESIS. PERO POR ELLO SE DESPLAZA EL FLANCO DE LA SEÑAL DE SALIDA CON EL TIEMPO EN RELACION AL PASO POR CERO DE LA SEÑAL DE ENTRADA. NO OBSTANTE, A VECES EXISTE LA EXIGENCIA DE QUE LOS FLANCOS ESTEN SINCRONIZADOS CON LOS PASOS POR CERO. POR TANTO, ES TAREA DE LA INVENCION ESPECIFICAR UNA DISPOSICION DE CIRCUITO QUE SATISFAGA ESTA EXIGENCIA. LA TAREA SE SOLUCIONA EN LA DISPOSICION DE CIRCUITO REIVINDICADA, PORQUE SE EMPLEA UN COMPARADOR (K1) CON HISTERESIS CONECTABLE ADICIONALMENTE, QUE SE CONECTA AL PASO POR CERO DE LA SEÑAL DE ENTRADA Y QUE TODAVIA ANTES DE LA APARICION DEL SIGUIENTE PASO POR CERO ESTA HISTERESIS SE ANULA DE NUEVO, DE FORMA QUE EL COMPARADOR (K1) SE CONMUTA OTRA VEZ EXACTAMENTE EN EL PASO POR CERO. ESTA DISPOSICION DEL CIRCUITO ES APROPIADA EN PARTICULAR PARA LA REGULACION DE MOTORES EN GRABADORES DE VIDEO.
