Eyona ndlela yoKwamkelwa kweMiqondiso yeDijithali
Kwinkqubo yonxibelelwano lwedijithali, umamkeli ufumana isixa somqondiso ogqithisiweyo kunye nengxolo yesitishi. Ukwamkelwa ngokufanelekileyo kweempawu zedijithali ezisekelwe kwimilinganiselo "engcono" kunye neyona mpazamo incinci inokwenzeka. Iimpazamo eziqwalaselwe kwesi sahluko ikakhulu ngenxa ye-band-limited ...Funda ngokugqithisileyo

Ukuqulunqwa kweNkqubo yeDigital Baseband yoThutho loMqondiso
Umzobo we-6-6 ngumzobo webhloko wenkqubo yokuhanjiswa kwesignali ye-digital baseband eqhelekileyo. Ikakhulu yenziwe sisihluzo sothumelo (ijenereyitha yomqondiso wetshaneli), itshaneli, isihluzo solwamkelo, kunye nesigqibo sesampulu. Ukuze kuqinisekiswe ukusebenza okuthembekileyo nocwangco ku...Funda ngokugqithisileyo

Intshayelelo yeDigital Baseband Signal Waveforms
Isiginali ye-baseband yedijithali yindlela yamaza ombane emele ulwazi lwedijithali, olunokuthi lumelwe ngamanqanaba ahlukeneyo okanye iipulses. Kukho iintlobo ezininzi zemiqondiso ye-baseband yedijithali (emva koku kuthiwa yimiqondiso ye-baseband). Umzobo 6-1 ubonisa iifom ezimbalwa ezisisiseko ze-baseband signal waveforms, ...Funda ngokugqithisileyo

Ukufunda ngoMqondiso
Iimpawu zokuvuma zingahlulwa zibe yimiqondiso yamandla kunye nemiqondiso yamandla ngokwamandla abo. Imiqondiso yamandla inokwahlulwa ibe yimiqondiso yamaxesha athile kunye nemiqondiso ye-aperiodic ngokungqinelana nokuba ngaba ngamaxesha athile okanye hayi. Umqondiso wamandla unomda kwi-amplitude kunye nobude bexesha, amandla ayo alungile ...Funda ngokugqithisileyo

Ulwahlulo lokuphindaphinda ngokuphindaphindiweyo
Xa umthamo wokuhambisa umjelo womzimba uphezulu kunemfuno yomqondiso omnye, umjelo unokwabelwana ngemiqondiso emininzi. Ngokomzekelo, umbombo wenkqubo yemfonomfono udla ngokuba namawakawaka emiqondiso ethunyelwa kwi<em>optical fiber enye. I-Multiplexing yitekhnoloji exazulula...Funda ngokugqithisileyo - Ngu Admin / 11 Aug 22 /0Amagqabantshintshi
Iintlobo zeKhowudi eqhelekileyo yoThutho lweBaseband
1) Ikhowudi ye-AMI Igama elipheleleyo lekhowudi ye-AMI (Alternative Mark Inversion) yenye ikhowudi yokuguqula uphawu. blank) ihlala ingatshintshi. Umzekelo: Ikhowudi yomyalezo: 0 1 1 0 0 0 0 0 0 0 0 1 1 0 0 1 1… AMI khowudi: 0 -1 +1 0 0 0 0 0 0 0 0 0 -1 +1 0 0 0 -1 +1… Ifom yamaza ehambelana nekhowudi ye-AMI yi...Funda ngokugqithisileyo
