Kānana Band Pass: Hoʻololi hou i ka ʻoihana uila

Ma keʻano he alakaʻi alakaʻi o nā mea uila, haʻaheo mākou e hoʻolauna i nā mea hou loa i kā mākou laina huahana - ka Kānana Kānāwai Kānāwai (BPF). ʻO nā BPF nā ʻāpana uila passive i kūkulu ʻia e ʻae i kahi ʻano o nā alapine e hele i loko, ʻoiai ke kāohi nei i nā mea ʻē aʻe. Ma kēia pou blog, e ʻimi mākou pehea e hoʻohana ʻia ai nā BPF i ka ʻoihana uila e hana i nā huahana maikaʻi aʻe a hoʻonui i ka hana.

He aha ka Band Pass Filter?

ʻO kahi kānana Band Pass kahi ʻano kānana uila e hiki ai i kahi ʻano kikoʻī o nā alapine ke hele ma kāna kaapuni. Hoʻopau ikaika kēia kānana i nā alapine āpau ma waho o ka bandwidth i makemake ʻia, e lilo ia i mea hana pono no ka hana hōʻailona. Hoʻohana ʻia nā noi o nā BPF i loko o ka Electronics IndustryBPFs ma nā ʻano hana like ʻole, me ke kelepona, nā leo a me nā wikiō, a me nā mea lapaʻau.

Eia nā noi nui loa o nā BPF i ka ʻoihana uila.

Kūkākūkā ueaʻole:Hoʻohui pinepine ʻia nā kānana Band Pass i nā ʻōnaehana kamaʻilio uila, e like me nā kelepona paʻa, e mālama i kahi hōʻailona paʻa. ʻOi aku ka maikaʻi o nā BPF i ka wā e hoʻopau ai i nā hōʻailona o waho, hiki ke hoʻopilikia a hōʻemi i ka maikaʻi o ka hōʻailona.

Leo a me ka wikiō:Hoʻohana pū ʻia nā kānana Band Pass i nā ʻōnaehana leo e pale ai i nā pae alapine i makemake ʻole ʻia mai ka hele ʻana. Hiki iā lākou ke hana i ka leo kiʻekiʻe me ka walaʻau ʻole a i ʻole distortion. I ka hana wikiō, ua lilo nā BPF i mea pono no ka hana ʻana i nā kiʻi HD. Hoʻomaʻamaʻa lākou i ka wehe ʻana i nā alapine makemake ʻole a me nā harmonic i ka wā e mālama ana i ka laulā i makemake ʻia.

Nā lako lāʻau lapaʻau:Ua lilo nā BPF i mea pono i nā mea lapaʻau e like me nā mīkini hoʻohālikelike magnetic (MRI). Ma ke kāohi ʻana i nā alapine ma waho o ka laulā i makemake ʻia, hana lākou i nā kiʻi akaka. Pēlā nō, hoʻohana ʻia lākou i loko o nā kānana koko e kānana ʻulaʻula a me nā keʻokeʻo keʻokeʻo mai ka hāpana.

I ka hopena, ʻo Band Pass Filters nā mea hana ikaika e hiki ke hoʻonui i ka hana o nā mea uila. ʻO ko lākou hiki ke kāohi i nā alapine makemake ʻole a hoʻonui i ka ratio signal-to-noise e pono ai lākou i nā ʻano noi.

Ma keʻano he alakaʻi alakaʻi o ka uila, haʻaheo mākou i ka hoʻohui ʻana i kēia ʻenehana i kā mākou huahana e hāʻawi i ka hana kiʻekiʻe loa i kā mākou mea kūʻai. ʻO kona kūpono i ka hoʻonui ʻana i ka hana o nā kaapuni uila e hana i nā kānana Band Pass i mea koʻikoʻi i ka ʻoihana uila.

ʻO Si Chuan Keenlion Microwave he koho nui i nā hoʻonohonoho ʻokoʻa a me ka broadband, e uhi ana i nā alapine mai 0.5 a 50 GHz. Hoʻolālā ʻia lākou e lawelawe mai ka 10 a 30 watts mana hoʻokomo i loko o kahi ʻōnaehana hoʻouna 50-ohm. Hoʻohana ʻia nā hoʻolālā Microstrip a i ʻole stripline, a hoʻopaʻa ʻia no ka hana maikaʻi loa.

Hiki nō iā mākou hoʻopilikino ka rf Band Pass Filter e like me kāu mau koi. Hiki iā ʻoe ke komo i ka ʻaoʻao hoʻoponopono e hāʻawi i nā kikoʻī āu e pono ai.
