ʻO nā kānana alapine kiʻekiʻe he mau mea uila i hoʻolālā ʻia e ʻae i kahi kikoʻī kikoʻī wale nō o nā hōʻailona alapine kiʻekiʻe e hele ma ke ʻano o ka hōʻemi ʻana i nā hōʻailona ma nā alapine ma waho o ia pae. Hoʻohana pinepine ʻia kēia mau kānana i nā ʻōnaehana kamaʻilio, nā lako leo, a me nā noi uila ʻē aʻe e koi ana i ka pane alapine pololei. Ma kēia ʻatikala, e ʻimi mākou i nā hiʻohiʻona koʻikoʻi o nā kānana pass band frequency kiʻekiʻe, me kā lākou pane alapine, bandwidth, a me Q-factor.
Pane alapinepine: ʻO ka pane alapine o kahi kānana ala alapine kiʻekiʻe e hoʻoholo ai pehea e hoʻemi ai i nā hōʻailona ma nā alapine ma waho o ka passband a me ka nui o ka hoʻonui ʻana i nā hōʻailona i loko o ka passband. E loaʻa i kahi kānana ala alapine kiʻekiʻe i hoʻolālā maikaʻi ʻia ma waena o ka passband a me ka stopband, me ka liʻiliʻi liʻiliʻi o ka passband. Hoʻoholo ʻia ke ʻano o ka pihi pane alapine e ka hoʻolālā o ka kānana, a hiki ke ʻike ʻia e kona alapine waena a me kona bandwidth.
Bandwidth: ʻO ka bandwidth o kahi kānana alapine kiʻekiʻe ka laulā o nā alapine i ʻae ʻia e hele i ka kānana me ka liʻiliʻi o ka attenuation. Hōʻike maʻamau ia ma ke ʻano he ʻokoʻa ma waena o nā alapine kiʻekiʻe a me lalo -3 dB, ʻo ia nā alapine i hoʻemi ʻia ai ka mana o ka kānana e 50% pili i ka mana kiʻekiʻe o ka passband. ʻO ka bandwidth o kahi kānana alapine kiʻekiʻe he mea koʻikoʻi e hoʻoholo ai i kāna koho a pehea e hiki ai iā ia ke hōʻole i nā hōʻailona makemake ʻole ma waho o ka passband.
Q-Factor: ʻO ka Q-factor o kahi kānana alapinepine kiʻekiʻe kahi ana o kona koho a ʻoi paha o ka pane alapine o ka kānana. Ua wehewehe ʻia ʻo ia ka ratio o ke alapine waena i ka bandwidth. ʻO kahi Q-factor kiʻekiʻe e pili ana i ka bandwidth haiki a me ka pane alapine ʻoi aku ka maikaʻi, aʻo ka Q-factor haʻahaʻa e pili ana i kahi bandwidth ākea a me ka pane pinepine ʻana. ʻO ka Q-factor o kahi kānana pass band frequency kiʻekiʻe he mea nui e hoʻoholo ai i kāna hana i ka hōʻole ʻana i nā hōʻailona makemake ʻole ma waho o ka passband.
Nalo Hoʻokomo: ʻO ka poho hoʻokomo ʻana o kahi kānana pass band frequency kiʻekiʻe ka nui o ka attenuation hōʻailona e hana ʻia ke hele ka hōʻailona ma ka kānana. Hōʻike maʻamau ia i nā decibels a he ana ia o ka nui o ka kānana atenuates i nā hōʻailona ma ka passband. ʻO kahi kānana alapinepine kiʻekiʻe i hoʻolālā maikaʻi ʻia e loaʻa ka liʻiliʻi o ka hoʻokomo ʻana i ka passband e pale aku i ka hoʻohaʻahaʻa ʻana i ka maikaʻi o ka hōʻailona.
Impedance Matching: ʻO ka hoʻohālikelike impedance kahi hiʻohiʻona koʻikoʻi o nā kānana pass band frequency kiʻekiʻe, ʻoi loa i nā ʻōnaehana kamaʻilio. Pono e hoʻohālikelike ʻia ka impedance hoʻokomo a me ka hoʻopuka o ka kānana i ke kumu a me ka hoʻouka impedance e hōʻemi i ka noʻonoʻo ʻana i ka hōʻailona a me ka hoʻololi ʻana i ka hōʻailona. ʻO kahi kānana alapinepine kiʻekiʻe i hoʻohālikelike maikaʻi ʻia e loaʻa ka liʻiliʻi o ka nalowale o ka hōʻailona a me ka distortion.
I ka hopena, ʻo nā kānana alapine kiʻekiʻe nā mea pono i nā kaapuni uila e koi ai i ka pane alapine pololei. ʻO kā lākou mau hiʻohiʻona koʻikoʻi ko lākou pane pinepine, bandwidth, Q-factor, insertion loss, a me ka hoʻohālikelike impedance. Pono e loaʻa i kahi kānana alapine kiʻekiʻe i hoʻolālā maikaʻi ʻia i ka pane alapine ʻoi, ka bandwidth haiki, ka liʻiliʻi o ka hoʻokomo ʻana, a me ka hoʻohālikelike impedance e hōʻoia i ka hana maikaʻi loa.
