Abstract
Kodlamada, bir akustik sinyalden türetilmiş olan bir frekans bölgesi örnek dizisi, ağırlıklı bir zarfla bölünür ve daha sonra bir kazançla bölünür, elde edilen sonuç nicelendirilir ve her bir örnek değişken uzunluklu olarak kodlanır. Niceleme öncesi örnek ile niceleme sonrası örnek arasındaki hata, bu değişken uzunluktaki kodlamaya kaydedilen bilgiler ile nicelendirilir. Bu niceleme işlemi, kaydedilen bit sayısına, hataları nicelenecek olan örneklere göre belirlenen bir kural çerçevesinde gerçekleştirilir. Kod çözme işleminde, bir frekans alanı örnek dizisi elde etmek için, kodların bir giriş dizisindeki değişken uzunluklu kodların kodu çözülür; bundan başka, bir hata sinyali değişken uzunluktaki kodların bit sayısına bağlı olan bir kural çerçevesinde çözülür; ve elde edilen örnek dizisinden, orijinal örnek dizisi, ek bilgilere göre elde edilir.
