Abstract

SISTEMA PARA EFECTUAR UNA DISCRIMINACION ENTRE EL IMPACTO DE UN OBJETO DURO DETECTADO POR UN TRANSDUCTOR Y EL RUIDO DE FONDO O LOS IMPULSOS DE RUIDO ELECTRICO. UNA SEÑAL DE IMPACTO (2) SE COMPARA EN EL COMPARADOR (OA1) CON UN PUNTO DE REGLAJE DE NIVEL (3) QUE NO ES FIJO, SINO QUE POR EL CONTRARIO SIGUE LOS CAMBIOS DE NIVEL DE RUIDO DE FONDO. LA SALIDA DEL COMPARADOR SE APLICA A UN DISCRIMINADOR DE SEÑAL DE IMPACTO QUE DETECTA UN NUMERO PREDETERMINADO DE PUNTOS DE CRUCE CONSEVUTIVOS (AB, A'', B'') RESPECTO AL PUNTO DE REGLAJE, EN UN PERIODO DE TIEMPO PREDETERMINADO, POR MEDIO DE (6) Y QUE DETECTA TAMBIEN UN NUMERO PREDETERMINADO DE ESTOS PERIODOS DE TIEMPO.
