1) ʻO ke alapine cutoff band fp=wp/(2p) ʻo ia ke alapine o ka palena palena ma waena o ka pā hele a me ka wahi hoʻololi, a hāʻule ka loaʻa hōʻailona ma ia wahi i ka palena haʻahaʻa o kahi hoʻonohonoho hana;
2) ʻO ke alapine ʻoki ʻoki puʻupuʻu fr=wr/(2p) ʻo ia ke alapine o ke kiko palena ma waena o ka pūʻali a me ka ʻāpana hoʻololi, a hāʻule ka pohō o ka hōʻailona i ka palena haʻahaʻa o ke kanaka;
3) ʻO ke alapine hoʻololi fc=wc/(2p) ʻo ia ka alapine o ka hōʻailona mana attenuation i 1/2 (e pili ana i 3dB), i nā manawa he nui, hoʻohana pinepine ʻia ʻo FC ma ke ʻano he pass a i ʻole ke alapine cutoff band;
4) ʻO ke alapine maoli f0=w0/(2p) ʻo ia ka wā ʻaʻohe poho o ke kaapuni, ʻo ke alapine resonant o ka kānana, nā kaapuni paʻakikī he mau alapine kūlohelohe.
ʻAʻole mau ka loaʻa ʻana o ka kānana i loko o ka pā.
1) no ka kānana ala haʻahaʻa ma o ka band gain KP e pili ana i ka loaʻa ke w=0;ʻO ke ala kiʻekiʻe e pili ana i ka loaʻa ma ka w→∞;me nā lula maʻamau e pili ana i ka loaʻa ma ke alapine waena;
2) no ka kānana Resistance band, pono e hāʻawi ʻia ka hoʻohana ʻana i ke kāʻei, a ʻo ka hoʻohana ʻana i ka palaho e wehewehe ʻia e like me ke ʻano o ka loaʻa;
3) Hoʻololi ka leo hoʻololi i ka band gain KP i ka hoʻololi kiʻekiʻe o ka loaʻa o kēlā me kēia kiko i loko o ka pahu, a inā aia ʻo KP i ka db, pili ia i ka nui o ka hoʻololi ʻana o ka waiwai DB loaʻa.
ʻO ka coefficient damping ka hana o ka hoʻohālikelike ʻana i ke alapine diagonal o ka kānana e like me ka hōʻailona w0, a he kuhikuhi ia e hōʻike ai i ka palaho o ka ikehu ma ka kānana.Ua kapa ʻia ka hoʻohuli ʻana o ka coefficient damping ʻo ke kumu maikaʻi, ʻo ia ka helu helu koʻikoʻi o nā hiʻohiʻona koho alapine o * Valence band pass a me band resistance Kānā, q= w0/W.
ʻO ka W i loko o ka formula ka 3dB bandwidth o ka band-pass a i ʻole ka band-resistance kānana, ʻo ka W0 ke kikowaena waena, a i nā manawa he nui ke alapine waena e like me ke alapine maoli.
Hoʻopaʻa ʻia ka ʻike o kahi hōʻailona hana y o kahi kānana i ka hoʻololi X o kahi ʻāpana ʻāpana i hoʻopaʻa ʻia e like me SXY, i wehewehe ʻia penei: sxy= (dy/y)/(dx/x).
ʻAʻole manaʻo ka sensitivity me ka sensitivity o ka mea ana a i ʻole ka ʻōnaehana kaapuni, a ʻo ka liʻiliʻi o ka ʻike, ʻoi aku ka ikaika o ka hoʻomanawanui hewa o ke kaapuni a ʻoi aku ka kiʻekiʻe o ke kūpaʻa.
