1 Ko te Polar e whakawhirinaki ana ki te tohu RF punaha.Mena kaore he tohu RF i roto i te punaha, me pai te polar.Ka nui ake te kaha o te tohu RF i tetahi taumata, ka huri te polar mai i te pai ki te kino.I tenei wa, ka huri te tohu Null me te Peak point tetahi ki tetahi.Ko te tohu Q+ me te tohu-Q ka huri tetahi ki tetahi.Ko te whakawhiti polar ka taea e te kaiwhakamahi te huri i te
polar tika me te kore e huri i nga tohu mahi.
