Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA TRANSFORMACION ANALOGICA-DIGITAL DE SEÑALES Y A UNA DISPOSICION PARA LA REALIZACION DEL PROCEDIMIENTO, DONDE LA ZONA DE UTILIZACION DE LA INVENCION SE ENCUENTRA EN LA TECNICA DE SENSORES, EN LA TECNICA DE MEDICION, EN LA TECNICA DE AUDIO Y TAMBIEN EN OTRAS ZONAS DE UTILIZACION DE MICROPROCESADORES ESPECIFICOS DE APLICACION. DE ACUERDO CON LA INVENCION SE CONSIGUE EL OBJETIVO DE TAL MODO, QUE SE OBTIENE UN PROCEDIMIENTO Y UNA DISPOSICION PARA TRANSFORMACION A/D DE SOLTADO DE ALTO DESARROLLO BAJO UTILIZACION DE UNA CANTIDAD REDUCIDA DE CONVERTIDORES A/D, DE TAL MODO, QUE LA SEÑAL ANALOGICA A SER DIGITALIZADA SE DIGITALIZA MEDIANTE MULTIPLES CONVERTIDORES A/D DE SOLTADO DE ALTO DESARROLLO, RESPECTIVAMENTE CON AMPLIFICACION PREVIA DIFERENTE CON LA POSIBILIDAD CORRESPONDIENTE. A CONTINUACION LOS CONVERTIDORES A/D RESPECTIVOS SE VALORAN CON LA DISPOSICION DE SOLTADO ADECUADA DE LAS SEÑALES MOMENTANEAS Y SE CALCULA POR ELLO LA SEÑAL DE SALIDA DIGITALDE LA DISPOSICION, DONDE DEBEN SER CONOCIDAS LAS AMPLIFICACIONES PREVIAS EN SITUACION INDIVIDUAL NO EXACTA, SINO QUE DEBEN SER DETERMINADAS ESPECIALMENTE CON LA AYUDA DE LAS SEÑALES DIGITALES GENERADAS EN LA TRANSFORMACION.
