Phase modulator - Pamberi sumo
Hwaro hwechikamu modulator modulation:
Redhiyo frequency chiratidzo ine inotenderera inotakura muchimiro che sine wave, inova hwaro hwechiratidzo. Iyo instantaneous amplitude inotevera curve iyi munzira yakanaka uyezve yakaipa, ichidzokera kunzvimbo yekutanga mushure mekutenderera kumwe kuzere - inoteedzera curve ye sine wave. Sine wave inogona zvakare kumiririrwa nekufamba kwakatenderedza nzvimbo mudenderedzwa, uye chikamu pane chero nzvimbo yakapihwa iAngle pakati pekutangira uye poindi pane waveform. Chikamu chinofambirawo mberi nekufamba kwenguva, saka mapoinzi pane waveform anogona kunzi ane mutsauko pakati pavo. Phase modulation inoshanda nekugadzirisa chikamu chechiratidzo, ndiko kuti, kushandura chiyero icho poindi inofamba ichitenderedza denderedzwa. Kana modulation ikasaiswa, izvi zvinoshandura chikamu chechiratidzo. Mune mamwe mazwi, kumhanya kwekutenderera kwakatenderedza denderedzwa kunogadziriswa maererano nerevo. Nokuda kweizvi, zvakakosha kushandura kuwanda kwechiratidzo munguva pfupi. Mune mamwe mazwi, kana chikamu modulation chikaiswa kune chiratidzo, pane frequency shanduko, uye zvinopesana. Phase uye frequency zvakabatana zvisinga patsanuke nekuti chikamu chikamu che frequency.
CHINANGWA:Kuwedzera kupinza-kubuda kwekuparadzaniswa kwechikamu chese modulator nekupa zero setting circuit inoita kuti signal voltage kubva pakutyaira zero kana chiratidzo chemutakuri chekucheka chinoshandiswa.CONSTITUTION:Diode switch circuit 10 inhanho mashanu. yakaderera-pass sefa rudzi chinja redunhu uchishandisa PIN diode 12 uye 14; kana mavoltages akasiyana munzira anoshandiswa kune diode 12 uye 14 kubva kudunhu rekutonga 16, switch inotendeuka uye kana mavheti epamberi aiswa, diode 12 uye 14 maitiro kuti aumbe dunhu diki, nekudaro kucheka mutakuri. Kudzora dunhu 16 inoshandisa kumberi voltages kune diode 12 uye 14 inoiswa neinotakura-inochekwa-yekubvisa chiratidzo. Kutyaira dunhu 30, kana mutakuri wekucheka-kubvisa chiratidzo akaiswa kuburikidza nemutsara makumi mana, anodzora nechisimba chiratidzo chemagetsi kuti apiwe maviri-chikamu PSK modulator 20 kusvika zero.
