Li-filters tsa Bandstop / Notch Filter li bapala karolo ea bohlokoa lefapheng la likhokahano ka ho khetha ho nyenyefatsa maqhubu a itseng le ho hatella matšoao a sa batleheng.Li-filters tsena li sebelisoa haholo lits'ebetsong tse fapaneng ho matlafatsa ts'ebetso le ts'epahalo ea litsamaiso tsa puisano.
Li-filters tsa Bandstop li fumana ts'ebeliso e pharaletseng libakeng tse latelang:
Khatello ea Letšoao le Pheliso ea Tšitiso: Litsamaiso tsa puisano hangata li kopana le mefuta e fapaneng ea matšoao a tšitiso, joalo ka a tsoang lisebelisoa tse ling tse se nang mohala le litšitiso tsa phepelo ea motlakase.Litšitiso tsena li ka nyenyefatsa bokhoni ba ho amohela le ho thibela tšitiso ea sistimi.Li-filters tsa Bandstop li hatella matšoao a tšitiso ka mokhoa o ikhethileng, tse nolofalletsang sistimi ho amohela le ho sebetsana le mats'oao a lakatsehang ka katleho[[1]].
Frequency Band Selection: Lits'ebetsong tse ling tsa puisano, ho hlokahala hore u khethe lihlopha tse khethehileng tsa maqhubu bakeng sa phetisetso le kamohelo ea lets'oao.Li-filters tsa Bandstop li nolofaletsa khetho ea maqhubu ka ho khetha ho fetisa kapa ho fokotsa matshwao ka har'a mekhahlelo e itseng.Mohlala, puisanong ea waelese, lihlopha tse fapaneng tsa matšoao li ka hloka ts'ebetso le phetiso e fapaneng.Li-filters tsa Bandstop li thusa ho khetha le ho lokisa matšoao ka har'a lihlopha tse ikhethileng tsa maqhubu ho fihlela litlhoko tsa litsamaiso tsa puisano
Phetoho le Boikemisetso ba Letšoao: Li-filters tsa Bandstop li ka sebelisoa ho fetola karabelo ea khafetsa le ho fumana litšobotsi tsa matšoao lits'ebetsong tsa puisano.Litsamaiso tse ling tsa puisano li ka hloka ho fokotsoa kapa ho ntlafatsoa ha mats'oao ka har'a mefuta e itseng ea maqhubu.Li-filters tsa Bandstop, ka moralo o nepahetseng le tokiso ea paramethara, li lumella phetoho ea matšoao le ntlafatso ho ntlafatsa boleng ba puisano le ts'ebetso ea sistimi.
Khatello ea Lerata la Matla: Lerata la phepelo ea motlakase ke taba e tloaelehileng lits'ebetsong tsa puisano.Lerata la phepelo ea motlakase le ka ata ho lisebelisoa tsa puisano ka lithapo tsa motlakase kapa marang-rang a phepelo, e leng se bakang tšitiso ea ho amohela le ho fetisa molaetsa.Li-filters tsa Bandstop li ka sebelisoa ho hatella ho phatlalatsoa ha lerata la phepelo ea motlakase, ho netefatsa ts'ebetso e tsitsitseng le kamohelo e nepahetseng ea matšoao lits'ebetsong tsa puisano.
Lisebelisoa tse fapaneng tsa li-filters tsa bandstop lefapheng la likhokahano li kenya letsoho haholo ho ntlafatsa ts'ebetso ea sistimi le ts'epahalo.Ka ho khetha ho hatella matšoao a tšitiso, ho nolofalletsa khetho ea lihlopha tsa maqhubu, ho lokisa matšoao, le ho hatella lerata la phepelo ea motlakase, li-bandstop filters li ntlafatsa phetisetso ea mats'oao le boleng ba kamohelo, li fihlela litlhoko tse fapaneng tsa litsamaiso tsa puisano.
