Isithombe Esifakiwe sesitifiketi se-FCC sase-United States

Isitifiketi sase-United States FCC

incazelo emfushane:

Isitifiketi se-FCC siyisitifiketi se-EMC esiyisibopho e-United States, esihloselwe kakhulu imikhiqizo kagesi nekagesi esukela ku-9KHz ukuya ku-3000GHz. Okuqukethwe kuhlanganisa izici ezehlukene ezifana nomsakazo, ukuxhumana, ikakhulukazi izindaba zokugxambukela komsakazo ezintweni zokuxhumana ezingenazintambo kanye nezinhlelo, okuhlanganisa imikhawulo yokuphazamiseka komsakazo nezindlela zokulinganisa, kanye nezinhlelo zokunikeza izitifiketi kanye nezinhlelo zokuphatha zenhlangano. Injongo iwukuqinisekisa ukuthi izinto zikagesi azibangeli ukuphazamiseka kwamanye amadivaysi kagesi futhi zithobelana nezimfuneko zemithetho nezimiso zase-US.
Incazelo yesitifiketi se-FCC iwukuthi zonke izinto zikagesi ezingenisiwe, ezithengiswayo, noma ezihlinzekwe emakethe yase-US kufanele zithobelane nezimfuneko zesitifiketi se-FCC, ngaphandle kwalokho zizobhekwa njengemikhiqizo engekho emthethweni. Izobhekana nezijeziso ezifana nenhlawulo, ukushaqwa kwezimpahla, noma ukwenqatshelwa kokuthengisa.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Lapho ukala ukucaca kwezithombe ezirekhodiwe zesignali yedijithali, ukuphakama kokulungiswa, isithombe sicace kakhudlwana. Ngokufanayo, umsindo wedijithali nawo "unokulungiswa" kwawo ngoba amasiginali edijithali awakwazi ukurekhoda umsindo womugqa njengamasiginali we-analogi, futhi angenza kuphela ijika lomsindo lisondele kulayini. Futhi i-Hi-Res iwumngcele wokulinganisa izinga lokubuyiselwa komugqa.
