Li-filters tse phahameng li sebelisoa hangata ho li-audio, video, le ts'ebetso ea litšoantšo ho ntlafatsa ho hlaka le ho fokotsa lerata.Ka mohlala:

1. Ts'ebetso ea molumo: Li-filters tse phahameng li ka sebelisoa ts'ebetsong ea molumo ho fokolisa lerata le tlaase-tlaase kapa matšoao a mang a sa hlokahaleng a tlaase, kahoo a ntlafatsa boleng ba molumo.
2. Ts'ebetso ea litšoantšo: Ha ho etsoa litšoantšo, li-filters tse phahameng li ka sebelisoa ho ntlafatsa lintlha tse phahameng-frequency litšoantšong, ho etsa hore li hlake haholoanyane.
3. Ts'ebetso ea lets'oao la kutlo: Li-filters tse phahameng li ka sebelisoa ho sefa lerata la maqhubu a tlase ho mats'oao a sensor, ka hona ho ntlafatsa ts'epahalo ea matšoao le ho nepahala.
4. Puisano ea seea-le-moea: Lipuisanong tsa seea-le-moea, li-filters tse phahameng li ka sebelisoa ho sefa mats'oao a maqhubu a tlase le tšitiso, ka hona ho ntlafatsa boleng ba puisano.

Qualwavee fana ka li-filters tse phahameng tsa ho hana li-high pass ka lebelo ho fihla ho 145GHz.Li-filters tse phahameng li sebelisoa haholo lits'ebetsong tse ngata.
