Abstract
Bir filtre sistemi, filtre tapların filtre dürtü yanıtı değerleri içeren alt bantlara karşılık gelen girdi alt bant filtre dürtü yanıtlarından sıkıştırılmış filtre dürtü yanıtları üretmek için bir filtre dönüştürücü (101) ve bir filtre sıkıştırıcı (102) içermektedir. Filtre sıkıştırıcısı (102), daha yüksek değerlere sahip filtre dürtü yanıtı değerlerini ve daha yüksek değerlerden daha düşük olan bir değere sahip en az bir filtre dürtü yanıtı değerini bulmak için en az iki giriş alt bant filtre giriş yanıtlarından filtre dürtü yanıtı değerlerinin incelenmesine ilişkin bir işlemciye (820) ve daha büyük değerlere sahip filtre dürtü yanıtı değerlerini kullanan sıkıştırılmış alt bant filtre dürtü yanıtlarının yapılmasına ilişkin bir filtre dürtü yanıtı yapıcıya (305) sahip, burada sıkıştırılmış alt bant filtre dürtü yanıtları, düşük değere sahip en az bir filtre dürtü yanıtı değerinin filtre kademelerine karşılık gelen filtre dürtü yanıtı değerlerini içermemekte ya da düşük değere sahip en az bir filtre dürtü yanıtı değerinin filtre kademelerine karşılık gelen sıfır değerli değerleri kapsamaktadır.
