      Yintoni iDiode? [Icacisiwe]

      I-Diode yenziwe nge-PN junction, kwaye i-photodiode inokuguqula isignali ye-optical ibe ngumqondiso wombane, njengoko kuboniswe ngezantsi: Ngokuqhelekileyo, i-covalent bond i-ionized xa i-PN junction ikhanya ngokukhanya. Oku kudala imingxunya kunye neeperi electron. Ifotocurrent yenziwe ngenxa...

      Yintoni iVCSEL laser?

      I-VCSEL, ebizwa ngokuba yi-Vertical Cavity Surface Emitting Laser ngokupheleleyo, luhlobo lwe-laser semiconductor. Okwangoku, uninzi lwe-VCSEL lusekwe kwii-semiconductors ze-GaAs, kwaye i-wavelength ekhutshwayo ikakhulu kwi-infrared wave band. Ngo-1977, uNjingalwazi u-Ika Kenichi weYunivesithi yaseTokyo yeTekhnoloji ufir...

      Yintoni iSalathiso saMandla oMqondiso esifunyenweyo (RSSI) ngokweenkcukacha

      I-RSSI sisishunqulelo seSalathiso soMqondiso oFunyiweyo waMandla. Uphawu lwamandla omqondiso olufunyenweyo lubalwa ngokuthelekisa amaxabiso amabini; oko kukuthi, inokusetyenziswa ukumisela ukuba yomelele okanye ibuthathaka kangakanani na amandla omqondiso xa kuthelekiswa nolunye uphawu. Ifomula yokubala yeRSSI...
