Na'urar rage ƙarfin ohms 75 wani nau'in na'urar rage ƙarfin ohms ne da aka sanya wa suna saboda ƙarfinsa na ohms 75.

Wani sinadari ne mai aiki da ake amfani da shi wajen daidaita ƙarfin siginar da'ira, na'urar rage siginar 75Ω tana hana ƙaruwa da karkacewar siginar da yawa, kuma tana hana lalacewa da siginar ke haifarwa.

Babban halayen attenuators na 75Ω sun haɗa da:

1. Daidaitawar Impedance: Impedance mai hana attenuator na 75 Ohms ya dace da yanayin impedance na layin watsa sigina na kayan aikin bidiyo, watsa shirye-shiryen talabijin da tsarin talabijin na kebul, don haka rage haske da asarar siginar watsawa.
2. Ƙarancin karkacewa: Mai rage ƙarfin siginar zai iya rage ƙarfin siginar ba tare da ƙara ƙarin karkacewa ko tsangwama ga siginar ba.
3. Babban aminci: Saboda gaskiyar cewa na'urorin rage zafi galibi kayan aiki ne marasa aiki kuma ba su da sassan motsi, suna da aminci sosai kuma ba sa buƙatar gyara ko maye gurbinsu.
