Lesi sici esiyingqayizivele senza isihlungi sethu sokwenqaba ibhendi silungele izinhlelo zokusebenza lapho amazinga athile emvamisa edinga ukususwa noma ancishiswe kakhulu. Kungakhathaliseki ukuthi udinga ukususa ukuphazamiseka okungafuneki noma ukuhlunga imvamisa ethile yomsindo, isihlungi sethu sokwenqaba ibhendi senzelwe ukuletha ukusebenza okuhle kakhulu nokunemba.

Isihlungi se-band reject siwuhlobo olukhethekile lwesihlungi se-band-stop, kanye nobubanzi baso be-stopband buncane kakhulu. Lokhu kuqinisekisa ukuthi ububanzi bemvamisa eqondiwe kuphela obuncishisiwe ngempumelelo, okushiya yonke enye isignali ingashintshi. Leli zinga lokunemba libalulekile ezimbonini eziningi, okuhlanganisa ezokuxhumana, ukucubungula umsindo, kanye nokusetshenziswa kwezinsimbi zikagesi.
