Abstract
Bir sayisal televizyon alicisi sabit simge hizina haiz alinmis sinyale NTSC sinyali karisimasini minimuma indirmek için bir filtre içerir. Bir esitleyici, her baglanti için iki adet bir-simge geciktirici içerir. Alinmis sinyalin filtreden geçirilmis ve filtreden geçirilmemis versiyonu esitleyicinin girisinde bir çoklayiciya uygulanir. Esitleyicideki arttiricilarin çiktilari birlestirilir ve bir çoklama kaldiriciya uygulanir. Filtreden geçirilmis ve filtreden geçirilmemis esitlenmis sinyaller mukayese edilir ve mukayeseye dayanarak filtreden geçirilmis ve filtreden geçirilmemis esitlenmis alinmis sinyallerin islenmesi için bir seçim yapilir.
