      Inqubo Engahleliwe Yohlelo Lokuxhumana

      Kokubili isignali nomsindo ekuxhumaneni kungathathwa njengezinqubo ezingahleliwe ezihluka ngokuhamba kwesikhathi. Inqubo engahleliwe inezici zokuguquguquka okungahleliwe kanye nomsebenzi wesikhathi, futhi ingachazwa ngemibono emibili ehlukene kodwa ehlobene eduze: ① inqubo engahleliwe iqoqo le...

      Imodi Yokudluliswa Kwedatha Yemodi Yokuxhumana

      Indlela yokuxhumana yindlela abantu ababili abakhuluma bodwa abasebenzisana ngayo noma ukuthumela imiyalezo. 1. Ukuxhumana kwe-Simplex, i-half-duplex kanye ne-full-duplex Ukuze uthole ukuxhumana kwephuzu kuya kwephuzu, ngokusho kwesiqondiso kanye nobudlelwane besikhathi sokudluliswa komlayezo, imodi yokuxhumana c...

      Ukwamukela Okungcono Kakhulu Kwezimpawu Zedijithali

      Ohlelweni lokuxhumana lwedijithali, umamukeli uthola isamba sesiginali edlulisiwe nomsindo wesiteshi. Ukwamukela okuphelele kwamasiginali edijithali ngokususelwe kumbandela “ongcono kakhulu” namathuba amancane ephutha. Amaphutha acatshangelwe kulesi sahluko ikakhulukazi ngenxa yomkhawulo webhendi ...

      Ukwakhiwa Kwesistimu Yokudluliswa Kwesiginali ye-Baseband Yedijithali

      Umdwebo 6-6 umdwebo we-block wesistimu yokudlulisa isignali ye-digital baseband evamile. Ikakhulukazi yakhiwe yisihlungi sokudlulisa (ijeneretha yesignali yesiteshi), isiteshi, isihlungi sokwamukela, kanye nesinqumo samasampuli. Ukuze kuqinisekiswe ukusebenza okuthembekile nokuhlelekile kwe-o...

      Isingeniso se-Digital Baseband Signal Waveforms

      Isignali ye-baseband yedijithali iwuhlelo lwamaza kagesi olumelela ulwazi lwedijithali, olungamelwa amazinga ahlukene noma ama-pulses. Kunezinhlobo eziningi zamasignali e-baseband yedijithali (ngemuva kwalokhu okubizwa ngokuthi amasignali e-baseband). Umfanekiso 6-1 ubonisa amaza e-baseband ayisisekelo esignali, ...

      Ukufunda Ngesiginali

      Izimpawu zokuvuma zingahlukaniswa zibe amasignali amandla kanye namasignali amandla ngokwamandla azo. Amasignali amandla angahlukaniswa abe amasignali ezikhathi ezithile kanye namasignali aperiodic kuye ngokuthi ayenzeka ngezikhathi ezithile noma cha. Isiginali yamandla inomkhawulo nge-amplitude kanye nobude besikhathi, amandla ayo fi...
