Chophatikizira cha FM ndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kuphatikiza ma transmitters a FM awiri kapena kupitilira munjira imodzi. Imathandizira ma transmitters angapo kugawana mlongoti umodzi, womwe umalola kugwiritsa ntchito pafupipafupi komanso kugwiritsa ntchito bwino ma radio sipekitiramu. Ophatikiza ma FM amadziwikanso kuti makina ophatikizira a FM, kuphatikiza makina, kapena kuphatikiza maukonde.

Kodi kuphatikiza kwa FM ndi kotani komwe kumagwiritsidwa ntchito kwambiri?
Zophatikizira za FM zimagwiritsidwa ntchito pamawayilesi owulutsa mawayilesi kuti aphatikize ma siginecha angapo amawayilesi amtundu womwewo panjira imodzi yotumizira kuti iwulutsidwe nthawi imodzi. Chimodzi mwazofala kwambiri zophatikizira ma FM ndikuphatikiza ma siginecha angapo a wayilesi ya FM kuti athe kuulutsidwa pa mlongoti womwewo. Kuphatikiza apo, ophatikiza ma FM amagwiritsidwa ntchito kuphatikiza ma siginecha a ma wayilesi angapo a FM omwe ali m'malo osiyanasiyana kuti apange chikwangwani chimodzi chophatikizika chomwe chitha kuulutsidwa kudera lalikulu.

Momwe mungasankhire zophatikizira zabwino kwambiri za ma transmitter a FM? Malingaliro ochepa...
Makasitomala ambiri amabwera kwa ife ndikufunsa, "Hey, ndi mitundu iti ya ma FM ophatikizira omwe amagulitsidwa omwe amadziwika kwambiri? Mtengo wa chophatikiza cha FMUSER UHF / VHF ndi chiyani?", Zomwe zili m'munsizi ndizokhudza momwe mungasankhire njira yabwino yophatikizira yanu. wailesi.

Kuti musankhe chophatikizira chabwino kwambiri cha FM pamawayilesi owulutsira, muyenera kuganizira zinthu monga kuchuluka kwa ma transmitter, mphamvu yomwe ilipo, kukula kwa tinyanga, ndi mtundu wa tinyanga tomwe timagwiritsidwa ntchito.
