1 Polar nyob ntawm qhov system RF teeb liab. Thaum tsis muaj RF teeb liab nyob rau hauv lub system, lub polar yuav tsum zoo. Thaum RF teeb liab muaj amplitude ntau dua ib theem, lub polar yuav hloov ntawm qhov zoo mus rau qhov tsis zoo. Lub sijhawm no, Null point thiab Peak point yuav hloov nrog ib leeg. Q + taw tes thiab Q- taw tes yuav hloov nrog ib leeg. Polar hloov ua rau cov neeg siv hloov pauv
polar ncaj qha yam tsis hloov cov ntsiab lus ua haujlwm.

1 Tsuas yog ib qho kev xaiv yuav tsum raug xaiv ntawm kev siv cov tswj photodiode lossis siv modulator photodiode. Nws raug nquahu kom siv tus maub los photodiode rau Lab kev sim rau ob qho laj thawj. Ua ntej, tus maub los photodiode tau ua kom zoo. Thib ob, nws yooj yim dua los kho cov tswv yim lub teeb siv. Yog tias siv modulator's internal photodiode, thov nco ntsoov tias cov zis tam sim no ntawm photodiode yog nruj me ntsis proportional rau input zog.
