Abstract

Bir ses sinyal işleme aparatı, bir birinci örnekleme frekansında örneklenen bir ses sinyalini alan bir alıcı (403) içermektedir, ses sinyali, bir birinci frekans kenar boşluğu tarafından birinci örnekleme frekansının yarısının altında bir maksimum frekansa sahiptir. Bir süzgeç kümesi (405), üst üste binen alt-süzgeçler kullanılarak dijital ses sinyali için altbant sinyallerini üretmektedir. Bir birinci frekans kaydırma cihazı (407), bir frekans kaymasını bir alt altbant takımının en az bir altbandına uygulamaktadır ve bir desimatör (409), üst üste binen alt-süzgeçlerin her birinin bir bant genişliğinin en az iki katı olan bir örnek olarak seyreltilmiş örnekleme frekansı ile sonuçlanan bir örnek seyreltme faktörü ile altbant sinyalini örnek olarak seyreltilmektedir. Bir altbanda yönelik frekans kayması, sıfırdan örnek olarak seyreltilmiş örnekleme frekansının yarısına kadar bir frekans aralığının bir katı olan bir frekans aralığına altbandın kayması için düzenlenmektedir. Altbant, ayrı ayrı işlenebilmektedir ve işlenmiş altbantlar, bir tambant çıktı sinyalinin üretilmesi için daha sonra katıştırılabilmektedir.
