Uhlalutyo lwebhendi kunye nokulinganisa

Iindibano zekhebula kunye nee-amplifier zingasetyenziselwa ukumisela i-bandwidth yokudluliselwa kwesignali, ukuhlalutya iimpawu zempendulo ye-frequency yesignali, kunye nokucubungula imiqondiso ye-RF. Ezi zixhobo zidlala indima ebalulekileyo ekuchanekeni nasekuthembekeni kohlalutyo lwe-bandwidth kunye nokulinganisa. Izicelo kuhlalutyo lwe-bandwidth kunye nokulinganisa ngokubanzi ziquka oku kulandelayo:

1. Ngokwesiqhelo isetyenziswa kuvavanyo lwe-bandwidth ukunceda ekumiseleni i-frequency ephezulu okanye i-bandwidth apho isignali inokuhamba khona.

2. Kuvavanyo lokuphendula rhoqo, olu vavanyo lungasetyenziselwa ukulinganisa ukuncitshiswa kunye nokuphuculwa kwemiqondiso kwiifrikhwensi ezahlukeneyo.

3. Ukuze kuqhutywe isignali ye-RF, isignali kufuneka ikhuliswe kwaye isasazwe kwinkqubo ukuqinisekisa ukuthembeka kokudluliselwa kwesignali.
