I-SAIC MG350/360/550/750 II-AUTO PARES CAR SPARE Phase modulator – Forward -10025921 Inkqubo yamandla UMBONELELI WEE-AUTO PARES WE-wholesale mg catalog ixabiso eliphantsi lasefektri.

Isiseko se-phase modulator modulation:

Isignali yerediyo ejikelezayo iqulathe isithwali esijikelezayo ngendlela ye-sine wave, esisisiseko sesignali. I-amplitude ekhawulezileyo ilandela le curve kwicala elihle nelibi, ibuyela kwindawo yokuqala emva komjikelo omnye opheleleyo - ilandela i-curve ye-sine wave. I-sine wave ingamelwa yintshukumo ejikeleze indawo kwisangqa, kwaye isigaba kuyo nayiphi na indawo yi-Angle phakathi kwendawo yokuqala kunye nendawo kwi-waveform. Esi sigaba sikwaqhubeka ngokuhamba kwexesha, ngoko ke amanqaku kwi-waveform kunokuthiwa anomahluko wesigaba phakathi kwawo. I-Phase modulation isebenza ngokuguqula isigaba sesignali, oko kukuthi, ukutshintsha isantya apho indawo ihamba khona kwisangqa. Ukuba i-modulation ayisetyenziswanga, oku kutshintsha isigaba sesignali. Ngamanye amazwi, isantya sokujikeleza esijikeleze isangqa siyaguqulwa ngokubhekiselele kwi-mean. Ngenxa yoku, kuyimfuneko ukutshintsha i-frequency yesignali ngexesha elifutshane. Ngamanye amazwi, xa i-phase modulation isetyenziswa kwisignali, kukho utshintsho lwe-frequency, kwaye ngokuchaseneyo. Isigaba kunye ne-frequency zidibene ngokungenakwahlulwa kuba isigaba siyinxalenye ye-frequency.

INJONGO: Ukwandisa ukwahlulwa kwe-input-output ye-phase modulator ngokubonelela ngesekethe yokuseta engu-zero eyenza i-signal voltage ukusuka kwisekethe yokuqhuba engu-zero xa kusetyenziswa isignali yokunqunyulwa komthwali.UMGAQO: Isekethe yokutshintsha i-diode 10 yisekethe yokutshintsha uhlobo lwe-filter olunezigaba ezintlanu olusebenzisa ii-PIN diodes 12 kunye ne-14; xa ii-voltages ezahlukeneyo kwicala zisetyenziswa kwii-diodes 12 kunye ne-14 ezivela kwisekethe yokulawula 16, iswitshi iyavuleka kwaye xa kusetyenziswa ii-voltages zangaphambili, ii-diodes 12 kunye ne-14 ziqhuba ukwenza i-short circuit, ngaloo ndlela zinqumla i-carrier. Isekethe yokulawula 16 isebenzisa ii-voltages zangaphambili kwii-diodes 12 kunye ne-14 ezisetyenziswa ngesignali yokunqunyulwa komthwali. Isekethe yokuqhuba 30, xa isignali yokunqunyulwa komthwali isetyenziswa ngomgca 40, ilawula ngenkani isignali ye-voltage eza kunikwa i-PSK modulator yezigaba ezibini 20 ukuya ku-zero.
