Imodyuli yesigaba sisiphaluka apho isigaba se-capriers save silawulwa sisiginali yokutsala. Zimbini iintlobo zemodyuli yesigaba seSine se-Sine Wave Umgaqo-siseko wokuqulunqa iphantsi INDAWO YOKUGQIBELA YENKQUBO YOKUQALA I-MODFLATIT YOKUQALA YOKUGQIBELA YOKUGQIBELA, UTSHINTSHO UTSHINTSHO UTSHINTSHO LWEZOBUCHULE BENKONZO, ukuze kufezekiswe imo yemo yenqanaba. Le ndlela yadalwa yiArmstrong ngo-1933, ebizwa ngokuba yiNdlela yeModstrong
I-shifter elawulwa nge-elektroniki ye-Microwave yinethiwekhi yezibuko ezimbini esetyenziselwa ukubonelela umahluko wesiseko phakathi kwemveliso kunye nemiqondiso enokuthi ilawulwe ngumqondiso wolawulo (ngokubanzi i-DC bias voltage). Isixa semigangatho yokutshintsha kwenqanaba inokwahluka ngokuqhubekayo ngomqondiso wolawulo okanye kwixabiso elimiselweyo elimiselweyo. Babizwa ngokuba ziishifti zeZigaba ze-ANAG kunye neDijithali yamanqanaba eDijithali ngokulandelelana. Imodyuli yeSigaba seMpuzi yeSigaba sokuHanjiswa kweSigaba sokuHamba kwi-Shift Shift Shift kwiNkqubo yokuNxibelelanisa i-microwave, esebenzisa amaza asisikwe esisikwere ukuba angayivumeli umqondiso. Imo yokumoda yesigaba seSine yahlulwahlulwahlulwa kwimozulu yenqanaba ngqo kunye nemodyuli yenqanaba elingathanga ngqo. Ngokusebenzisa ubudlelwane bokuba i-sne ye-ames ye-amevatude ye-Adle idityaniswe rhoqo, i-Rusquency Moduved Wave inokuguqulwa ibe sisigaba semodyuli (okanye ngokuchaseneyo). Esona setyhula iqhelekileyo yesekethe isetyenziswayo yemodyuli ye-vioctor ye-viode ye-viode. Iphenyane lemodyuli engathanga ngqo inzima ngakumbi kunesekethe yemo yemozulu yenqanaba. Umgaqo wayo kukuba enye indlela yomqondiso wothutho utshatiswa yi-90 ° I-shifter yenqanaba le-90 shifter kwaye ingena kwimodyuli ye-AMLLEX-I-MODLINE I-AMLINECR ukuze icinezele imo ye-alliveting yomphathi. Emva koxinzelelo olufanelekileyo, umqondiso ofunyenweyo wongezwa kwenye indlela yemoto yokukhupha umzobo we-AMDLLAIT. Esi siphaluka sibonakaliswa ziindawo eziphakamileyo zokuzinza eziphezulu, kodwa i-Shift yeSigaba seSigaba ingenakuba inkulu kakhulu (ngokubanzi ingaphantsi kwe-15 °) okanye ukugqwetha kakhulu. Imodyuli yesigaba esilula ihlala isetyenziswa kwiindawo zokusasaza ze-FM.
