Abstract

EL APARATO PARA CONTROLAR LA CONSTANTE DE TIEMPO DE UNA SEÑAL INCLUYE UN CONTADOR ARRIBA/ABAJO (20) PARA CONTAR LOS IMPULSOS DE UNA SEÑAL HORARIA. EL VALOR DE CUENTA ES UTILIZADO COMO SEÑAL DE SALIDA. LA SEÑAL DE SALIDA ES COMPARADA (12) CON LA SEÑAL DE ENTRADA PARA DAR UNA PRIMERA SEÑAL DE CONTROL DETERMINANTE DE SI EL CONTADOR CUENTA HACIA ARRIBA O HACIA ABAJO. LA SEÑAL DE SALIDA ES COMPARADA (14) CON LA COMPENSACION DE LA SEÑAL DE ENTRADA (10; 400) POR UN VALOR CONSTANTE PARA DAR UNA SEÑAL QUE ESTA COMPUESTA MEDIANTE EL OPERADOR OR (18) CON LA PRIMERA SEÑAL DE CONTROL, Y LA SEÑAL COMPUESTA MEDIANTE EL OPERADOR OR ES UTILIZADA PARA ACTIVAR/DESACTIVAR AL CONTADOR. LA APLICACION DE UN VALOR DE COMPENSACION CONSTANTE A LA SEÑAL DE ENTRADA PARA SER COMPARADA, EXCLUYE AL SISTEMA PARA CONTAR ALTERNATIVAMENTE HACIA ARRIBA Y HACIA ABAJO POR UNA UNIDAD DE VALOR DURANTE INTERVALOS DE SEÑALES DE ENTRADA CON UNA AMPLITUD RELATIVAMENTE CONSTANTE.
