Li-Filters tsa RF: Likarolo tsa Bohlokoa tsa Bohlokoa tsa Lisebelisoa tsa Puisano tse se nang Mehala

Lisebelisoa tsa RF, e le likarolo tsa mantlha tsa litsamaiso tsa likhokahano tse se nang mohala, li fihlella ntlafatso ea mats'oao le ho ntlafatsa boleng ba phetisetso ka ho khetha mats'oao a maqhubu. Lefatšeng la kajeno le hokahaneng haholo, karolo eaLisebelisoa tsa RFe ke ke ea hlokomolohuoa.
