1 Polar e ipapisitse le lets'oao la RF la sistimi. Ha ho se na lets'oao la RF tsamaisong, polar e lokela ho ba ntle. Ha lets'oao la RF le na le amplitude e kholo ho feta boemo bo itseng, polar e tla fetoha ho tloha ho e ntle ho ea ho e mpe. Ka nako ena, Null point le Peak point li tla chenchana.Q+ point le Q-point li tla chenchana hape.Polar switch e thusa mosebelisi ho fetola polar.
ka kotloloho ntle le ho fetola lintlha tsa ts'ebetso.
