Abstract
EN MUCHOS DETECTORES DE MEDICION ELECTRICOS, EL VALOR MEDIDO QUE SE HA DE DETECTAR SE CONVIERTE EN DOS SEÑALES DE MEDICION DE FRECUENCIA ANALOGA A PARTIR DE LAS CUALES SE DERIVA UNA FRECUENCIA DIFERENCIAL O UN COEFICIENTE DE FRECUENCIA PARA DETERMINAR LA MEDICION. A FIN DE ELIMINAR EL EFECTO DE LAS INTERFERENCIAS EN EL RESULTADO DE LA MEDICION Y PARA REDUCIR LA NO LINEARIDAD, CONFORME A ESTA INVENCION LA DETERMINACION DE LA MEDICION SE BASA EN LA DIFERENCIA ENTRE LA PROPORCION F SUB A/F SUB B DE LAS FRECUENCIAS F SUB A Y F SUB B DE DOS SEÑALES DE MEDICION Y SUS RECIPROCAS F SUB B/F SUB A. EN UNA INCORPORACION PREFERENTE DE LA INVENCION SE INTEGRA CON EL DETECTOR DE MEDICION EN UN CHIP SEMICONDUCTOR LA CORRESPONDIENTE DISPOSICION ELECTRICA PARA PROCESAR SEÑALES DE MEDICION.
