ʻO kaKānana Hoʻōki Band, (BSF) kekahi ʻano o ke kaapuni koho alapine e hana ana ma ke ʻano ʻē loa i ka Band Pass Filter a mākou i nānā ai ma mua. ʻO ke kānana hoʻōki band, i ʻike ʻia hoʻi he kānana hōʻole band, e hoʻouna i nā alapine āpau koe wale nō nā mea i loko o kahi band hoʻōki i kuhikuhi ʻia i hoʻēmi nui ʻia.
Inā he haiki loa kēia kaula hoʻōki a ua hoʻēmi nui ʻia ma luna o kekahi mau hertz, a laila ua kapa pinepine ʻia ka kānana hoʻōki kaula he kānana notch, ʻoiai ʻo kāna pane alapine (frequency) e hōʻike ana i kahi notch hohonu me ke koho kiʻekiʻe (kahi piʻo ʻaoʻao pali) ma mua o kahi kaula ākea i pālahalaha ʻia.
Eia kekahi, e like me ke kānana band pass, ʻo ke kānana band stop (band reject a notch paha) he kānana kauoha ʻelua (ʻelua-pole) nona nā alapine ʻoki ʻelua, i ʻike nui ʻia ʻo -3dB a i ʻole nā kiko hapa-mana e hana ana i kahi bandwidth band stop ākea ma waena o kēia mau kiko ʻelua -3dB.
A laila ʻo ka hana o kahi kānana hoʻōki hui, ʻo ia ke hoʻouna i kēlā mau alapine āpau mai ka ʻole (DC) a hiki i kona kiko alapine ʻoki mua (haʻahaʻa) ƒL, a hoʻouna i kēlā mau alapine āpau ma luna o kona alapine ʻoki lua (luna) ƒH, akā e ālai a hōʻole paha i kēlā mau alapine āpau ma waena. A laila ua wehewehe ʻia ka bandwidth o nā kānana, ʻo BW: (ƒH - ƒL).
No laila, no kahi kānana hoʻōki band wide-band, aia ke kaula hoʻōki maoli o nā kānana ma waena o kona mau kiko -3dB haʻahaʻa a me luna i kona hoʻēmi ʻana, a hōʻole paha i kekahi alapine (frequency) ma waena o kēia mau alapine ʻoki ʻelua. No laila, ua hāʻawi ʻia ke kiʻikuhi pane alapine (frequency response curve) o kahi kānana hoʻōki band kūpono.
ʻO ke kūponokānana hoʻōki huie loaʻa ka attenuation palena ʻole i loko o kāna kaula hoʻōki a me ka attenuation ʻole ma kēlā me kēia kaula pass. ʻO ka hoʻololi ma waena o nā kaula pass ʻelua a me ke kaula hoʻōki e kū pololei (pā pōhaku). Aia kekahi mau ala e hiki ai iā mākou ke hoʻolālā i kahi "Band Stop Filter", a hoʻokō lākou āpau i ke kumu like.
Hele mai nā ʻāpana me nā mea hoʻohui wahine SMA a i ʻole N, a i ʻole 2.92mm, 2.40mm, a me 1.85mm nā mea hoʻohui no nā ʻāpana alapine kiʻekiʻe.
Hiki iā mākou ke hoʻopilikino i kaKānana Hoʻōki Bande like me kāu mau koi. Hiki iā ʻoe ke komo i ka ʻaoʻao hoʻopilikino e hāʻawi i nā kikoʻī āu e pono ai.
