Ukuhlaziywa kwe-bandwidth nokulinganisa

Imihlangano ye-Cable kanye nama-amplifiers ingasetshenziswa ukuthola i-bandwidth yokudluliswa kwesiginali, hlaziya izimpawu zokuphendula kwezimpawu zemvamisa, bese ucubungula amasiginali we-RF. Lawa madivayisi adlala indima ebalulekile ngokunemba nangokuthembela kokuhlaziywa kwe-bandwidth nokulinganiswa. Izicelo ekuhlaziyweni kwe-bandwidth nokulinganisa ngokuvamile kufaka phakathi okulandelayo:

1. Ngokuvamile esetshenziswa ekuhlolweni kwe-bandwidth ukusiza ukunquma imvamisa ephezulu noma umkhawulokudonsa lapho isinali lingahamba ngalo.

2. Ukuhlolwa kokuphendula imvamisa, lokhu kuhlolwa kungasetshenziselwa ukukala i-attiation kanye nokwenza ngcono amasiginali ngamaza ahlukene.

I-3. Ngokucutshungulwa kwesiginali ye-RF, isiginali idinga ukukhuliswa futhi isatshalaliswe kwinqubo ukuqinisekisa ubuqotho bokudluliselwa kwesiginali.
