Abstract

Düşük bantlı bir sinyal kullanılarak geniş bantlı bir sinyalin üretilmesine yönelik bir aparat, yöntem ve bilgisayar programı, iletilmiş parametreler kullanılarak bir kılavuzlu bent genişliği uzatma işleminin ve iletilen parametreler yerine sadece elde edilmiş parametreler kullanılarak bir gözü kapalı bant genişliği uzatma işleminin gerçekleştirilmesine yönelik bir işlemciyi (23) içerir. Bu amaçla işlemci, gözü kapalı bant genişliği uzatma işlemine yönelik parametrelerin üretilmesine yönelik bir parametre üretecini (24) içerir.
