Abstract

METODO PARA EL CAMBIO DE LA CUOTA DE EXPLORACION DE UNA SEÑAL EXPLORADORA EN OTRA CUOTA DE EXPLORACION CON LAS SIGUIENTES ETAPAS DEL PROCESO: A) EN LA DISMINUCION DE LA CUOTA EXPLORADORA SE CONDUCE LA SEÑAL DE EXPLORACION GRACIAS A UN FILTRO DIGITAL, DE TAL MANERA QUE LA FRECUENCIA QUE SE MANIFIESTA CON MAYOR MAGNITUD, ESTA DENTRO DE UNA FRECUENCIA DE EXPLORACION MENOR O IGUAL A LA MEDIA NUEVA QUE SE CREA TRAS EL ESPECTRO QUE PRESENTA EL ANILLO DEL FILTRO. B) EN EL AUMENTO DE LA CUOTA EXPLORADORA SE CONDUCE LA SEÑAL DE EXPLORACION GRACIAS A UN FILTRO DIGITAL, DE TAL MANERA QUE EN EL CAMPO DE FRECUENCIA NO SE MANIFIESTAN NINGUNAS INTERFERENCIAS ESPECTRALES ENTRE MENOR O IGUAL QUE LA MITAD ORIGINARIA Y ENTRE LA MITAD DE LAS NUEVAS CUOTAS DE EXPLORACION. SOBRE LAS DEMANDAS REFERIDAS EN A) Y B) A LA LIMITACION DE LA CINTA SE PUEDE UTILIZAR EL FILTRO DIGITAL EN AMBOS CASOS, ES DECIR EN LA DISMINUCION Y EN EL AUMENTO DE LA CUOTA EXPLORADORA CON UNA LIMITACION DE LA CINTA AUN MAYOR Y/O TAMBIEN SEPUEDE UTILIZAR LA FORMACION ESPECTRAL A LA ENTRADA DE LA DISPOSICION PARA UN TRANSFORMADOR DE CUOTAS DE EXPLORACION. C) LA SEÑAL QUE SE ORIGINA SE SONDEA CON LA NUEVA CUOTA DE EXPLORACION.
