Aqoonta alaabta

Modulator-ka wajiga waa wareeg kaas oo wejiga mawjada side ay gacanta ku hayso calaamad wax-bedelka ah. Waxaa jira laba nooc oo qaabaynta wejiga sine wave: habaynta wejiga tooska ah iyo habaynta wejiga aan tooska ahayn. Mabda'a habaynta wejiga tooska ah waa in la isticmaalo calaamadda wax-ka-beddelka si toos ah loogu beddelo cabbirrada loop-ka resonant, si ay calaamad-qaaduhu u dhex maraan wareegga resonant si ay u abuuraan isbeddelka marxaladda oo ay u sameeyaan mowjadda habaynta wajiga; Habka qaabaynta wejiga aan tooska ahayn ayaa marka hore wax ka beddela baaxadda hirarka la beddelay, ka dibna waxa uu beddelka ballaadhsiga u beddelaa isbeddelka wejiga, si loo gaadho habaynta wejiga. Habkan waxaa abuuray Armstrong 1933, oo loo yaqaan Armstrong modulation method

Wareegtada mikrowave ee elektarooniga ah ee gacanta lagu hayo waa shabakad laba-dekedood ah oo loo isticmaalo in lagu bixiyo kala duwanaanshaha wejiga ee u dhexeeya soo-saarka iyo calaamadaha wax-soo-saarka kaas oo lagu xakameyn karo calaamadda kontoroolka (guud ahaan danabka DC). Qadarka wareegitaanka wejigu si joogto ah ayuu u kala duwanaan karaa calaamadda xakamaynta ama qiime gaar ah oo la sii go'aamiyay. Waxaa loo yaqaannaa shifiyeyaasha analoogga ah iyo wejiga wareega dhijitaalka ah siday u kala horreeyaan. Modulator-ka wajiga waa furaha furaha wajiga labanlaab ee nidaamka isgaarsiinta microwave, kaas oo adeegsada mowjad labajibbaaran oo joogto ah si uu u habeeyo calaamada qaadaha. Habaynta wejiga mawjadda sine waxa loo qaybin karaa habaynta wejiga tooska ah iyo habaynta wejiga tooska ah. Adigoo isticmaalaya xidhiidhka in xagasha baaxadda mawjadda sine ay udub dhexaad u tahay soo noqnoqoshada degdega ah, mowjadda waxka bedelka soo noqnoqda waxa loo bedeli karaa mowjad habaysan (ama lidkeeda). Wareegga modulator-ka wejiga tooska ah ee inta badan la isticmaalo waa modulator-ka wejiga diode-ka. Wareegga habaynta wejiga aan tooska ahayn waa ka dhib badan yahay wareegga habaynta wejiga tooska ah. Mabda'adeedu waa in hal dariiq oo calaamadda gudbiyaha ah uu u wareego 90° marxaladda wareejinta oo uu galo baaxadda-modulator-ka dheellitiran si loo xakameeyo qaab-dhismeedka baaxadda qaadaha. Ka dib markii si sax ah loo nuugo, signalka la helay waxaa lagu daraa dariiqa kale ee side si uu u soo saaro signalka wax-ka-beddelka. Wareeggan waxaa lagu gartaa xasillooni soo noqnoqota oo sarreeya, laakiin isbeddelka wejigu ma noqon karo mid aad u weyn (guud ahaan wax ka yar 15 °) ama qallooc daran. Modulator wejiga fudud ayaa inta badan loo adeegsadaa gudbiyaasha baahinta FM-ta.
