Abstract

Yanki bastiricilarini kontrol etmek için yöntemler ve düzenek çesitli kosullar altinda alinan sinyal kalitesini en uygun hale getirirken üstün yanki azaltmasi saglar. Tarif edilen teknikler bir yanki bastiricisinin gereginden fazla zayiflatma ve dolayisiyla daha çok sinyal bozulmasi yaratmasi olasiligini en aza indirirken arzu edilen yanki zayiflatma seviyelerini saglar. Birinci örnek uygulamada bir akustik yanki bastiricisi, bir ses aktivitesi algilayicisi, bir uzak-taraf iletisim sinyalinin konusma bileseni içermedigini belirttiginde devre disi birakilir.Ikinci örnek uygulamada, bir aktif akustik yanki iptal edicisinin zayiflatma faktörü bir ses aktivitesi algilayicisinin bir yakin-taraf iletisim sinyalinin bir yakin-taraf konusma bileseni içerip içermedigini belirtmesine dayanarak ayarlanir.Üçüncü örnek uygulamada, bir akustik yanki iptal edicisi tarafindan saglanan zayiflatma seviyesi akustik yanki iptal edicisine bir ses girisindeki ölçülen ses-gürültü oranina dayanarak ayarlanir.
