Iyo Yakanyanya Kugamuchirwa yeDigital Signals
Mudhijitari yekutaurirana sisitimu, anogamuchira anogashira huwandu hweiyo inofambiswa chiratidzo uye ruzha rwechiteshi. Iko kugashira kwakaringana kwemasaini edhijitari zvichibva pane "yakanakisa" chiyero ine diki kukanganisa kukanganisa. Mhosho dzakatariswa muchitsauko chino dzakanyanya kukonzerwa nebhendi-shoma ...Verenga Zvimwe

Kuumbwa kweDigital Baseband Signal Transmission System
Mufananidzo 6-6 ibhuroka dhayagiramu yeyakajairwa yedhijitari baseband chiratidzo chekufambisa system. Iyo inonyanya kuumbwa neyekufambisa sefa (chiteshi chiratidzo jenareta), chiteshi, sefa yekugamuchira, uye sampling yekusarudza. Kuti uve nechokwadi chekushanda kwakavimbika uye kwakarongeka ...Verenga Zvimwe

Nhanganyaya kune Digital Baseband Signal Waveforms
Chiratidzo chedhijitari baseband igetsi waveform inomiririra ruzivo rwedhijitari, iyo inogona kumiririrwa neakasiyana mazinga kana pulses. Kune akawanda marudzi edhijitari baseband masaini (pano anonzi masaini ebhendi). Mufananidzo 6-1 inoratidza mashoma ekutanga baseband signal waveforms, ...Verenga Zvimwe

Frequency Division Multiplexing
Kana iyo yekufambisa chiteshi chechani chemuviri chakakwira kupfuura kudiwa kwechiratidzo chimwe, chiteshi chinogona kugovaniswa nemasaini akawanda. Semuenzaniso, trunk line yenharembozha kazhinji ine zviuru zvezviratidzo zvinofambiswa pane imwe optical fiber. Multiplexing ndiyo tekinoroji inogadzirisa ...Verenga Zvimwe - Na Admin / 11 Aug 22 /0Comments
