Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO DE FILTRADO DE UNA SEÑAL ELECTRICA, EN PARTICULAR DE UNA SEÑAL DE MANDO DE LOGOMETRO PARA VEHICULOS AUTOMOVILES, CARACTERIZADO POR EL HECHO DE QUE COMPRENDE LAS ETAPAS QUE CONSISTEN EN : COMPARAR (100) CADA NUEVO VALOR RECIBIDO DE UNA SEÑAL DE ENTRADA (XN) CON UN VALOR DE SALIDA ANTERIOR (YN-1), COMPARAR (106, 114) LA DIFERENCIA (A) DETECTADA ENTRE DICHO NUEVO VALOR RECIBIDO (XN) DE LA SEÑAL DE ENTRADA Y EL VALOR DE SALIDA ANTERIOR (YN-1), CON UN VALOR DE UMBRAL PREDETERMINADO (P), MEMORIZAR UN VALOR DE REFERENCIA (ZN), RETOCAR EL VALOR DE CONSIGNA MEMORIZADA (ZN) MODIFICANDO EL VALOR DE REFERENCIA ANTERIOR (ZN-1) DEL VALOR DE UMBRAL PREDETERMINADO (P) SI DICHO VALOR DE UMBRAL PREDETERMINADO (P) ES INFERIOR A DICHA DIFERENCIA DETECTADA (A), O MODIFICANDO EL VALOR DE REFERENCIA ANTERIOR (ZN-1) DE DICHA DIFERENCIA DETECTADA (A), SI DICHO VALOR DE UMBRAL PREDETERMINADO (P) ES SUPERIOR A DICHA DIFERENCIA DETECTADA (A), Y DIVIDIR (120) EL VALOR DE REFERENCIA (ZN) POR UNA CONSTANTE (K) PARA FORMAR LA SEÑAL DE SALIDA (YN).
