Ka Hana ʻana i nā Hōʻailona Analog
He kahua koʻikoʻi a ākea ka hana ʻana i nā hōʻailona analog i ka ʻenekinia a me ka ʻepekema. ʻO nā hōʻailona analog nā hōʻike mau o nā hanana kino, e pili ana i nā loli e like me ke kaomi, ka mahana, ke kani, a me ke kukui. ʻAe ka hana ʻana i nā hōʻailona iā mākou e hoʻololi, hoʻomaikaʻi, a kālailai i kēia mau hōʻailona no nā ʻano noi like ʻole. E wehewehe kēia ʻatikala i nā kumu o ka hana ʻana i nā hōʻailona analog, nā ʻenehana koʻikoʻi, nā noi, a me nā pilikia.
Nā Kumu Hoʻohālikelike Analog
He hōʻailona hoʻomau ka hōʻailona analog e hiki ke loaʻa nā ʻano nalu like ʻole, e like me ke kani leo mai kahi mea kani a i ʻole ke wikiō mai kahi kāmela analog. Hoʻololi mau kēia mau ʻano nalu a loaʻa kahi loli mau o nā waiwai. ʻOkoʻa nā hōʻailona analog mai nā hōʻailona kikohoʻe, nona nā waiwai ʻelua wale nō: 0 a me 1.
Nā ʻano hōʻailona Analog
1. Amplitude: Ka nui a i ʻole ka ikaika o kahi hōʻailona ma kahi kikoʻī i ka manawa.
2. Alapine (Frequency): Ka helu o nā nalu e kū mai ana i hoʻokahi kekona, i ana ʻia ma Hertz (Hz).
3. Pae: Ke kihi a i ʻole ka neʻe ʻana o ka manawa o kahi nalu ma kahi kikoʻī.
He mea nui ka hoʻomaopopo ʻana i kēia mau ʻano kumu no ka hana hōʻailona hou aku.
Nā ʻenehana hana hōʻailona Analog
Hiki ke hana ʻia ka hana ʻana i nā hōʻailona analog me ka hoʻohana ʻana i nā ʻano hana a me nā ʻano hana like ʻole, ma muli o nā pahuhopu e hoʻokō ʻia.
1. Hoʻoikaika Hōʻailona (Hoʻonui)
ʻO ka hoʻonui ʻana i nā hōʻailona he ʻano hana ia no ka hoʻonui ʻana i ka amplitude o kahi hōʻailona me ka hoʻololi ʻole i kāna ʻike ʻike. Pono ka hoʻonui ʻana i ka wā nāwaliwali loa kahi hōʻailona e kālailai ʻia a hoʻohana hou ʻia paha. ʻO ka mea i hoʻohana ʻia he amplifier, hiki ke loaʻa ma ke ʻano o kahi amplifier hana (op-amp) i nā kaapuni uila.
2. Kānana ʻana
ʻO ka manaʻo o ke kānana hōʻailona e hoʻokaʻawale a wehe paha i kekahi mau ʻāpana alapine (frequency) i loko o kahi hōʻailona. Aia nā ʻano kānana like ʻole, me:
– Kānana haʻahaʻa-haʻahaʻa: Hoʻoili i nā alapine haʻahaʻa a mālama i nā alapine kiʻekiʻe.
– Kānana hele kiʻekiʻe: Hoʻoili i nā alapine kiʻekiʻe a mālama i nā alapine haʻahaʻa.
– Kānana Band-pass: Hoʻohele i kekahi mau alapine (frequency) a ālai i nā mea ʻē aʻe.
– Kānana hoʻōki-band: Hoʻopaʻa i kahi laulā alapine (frequency) a hoʻouna i nā mea ʻē aʻe.
He mea pono loa ka kānana ʻana i nā noi e like me ka wehe ʻana i ka walaʻau a me ka hoʻokaʻawale ʻana i nā hōʻailona i makemake ʻia mai ka spectrum alapine (frequency).
3. Hoʻololi
ʻO ka modulation kahi ʻano hana e kau ʻia ai kahi hōʻailona ʻike (hiki ke piggybacking) ma luna o kahi hōʻailona lawe me kahi alapine kiʻekiʻe. Hoʻomaʻalahi kēia i ka hoʻoili ʻana o nā hōʻailona ma luna o nā media e like me ka ea a i ʻole ke kaula. Aia kekahi mau ʻano modulation, me:
– Amplitude Modulation (AM): Hoʻopili ʻia ka ʻike me ka hoʻohana ʻana i nā ʻokoʻa o ka amplitude o ka hōʻailona lawe.
– Hoʻololi pinepine ʻia (FM): Hoʻopili ʻia ka ʻike ma o nā loli o ke alapine (frequency) o ka hōʻailona lawe.
– Phase Modulation (PM): Hoʻopili ʻia ka ʻike ma ka hoʻololi ʻana i ke kahua o ka hōʻailona lawe.
4. Hoʻololi ʻana i ke ʻano
ʻO ka demodulation ke kaʻina hana ʻē aʻe o ka modulation, e hoʻihoʻi ana i ka hōʻailona ʻike mai ka hōʻailona lawe i loaʻa. He mea nui kēia i nā ʻōnaehana kamaʻilio e hōʻoia i ka loaʻa ʻana o ka ʻike mua a wehewehe pololei ʻia.
5. Hoʻololi Fourier
ʻO ka loiloi Fourier, a i ʻole ka hoʻololi Fourier, e hoʻololi i kahi hōʻailona mai ka domain manawa i ka domain alapine. ʻAe kēia i ka nānā kikoʻī ʻana o nā ʻāpana alapine i loko o ka hōʻailona. He mea hana ikaika ka hoʻololi Fourier no ka ʻike ʻana i nā ʻano hōʻailona i ʻike koke ʻole ʻia ke kālailai ʻia ma ka domain manawa wale nō.
6. Hoʻololi ʻana i ka Microwave
He ʻenehana paʻakikī ka hoʻololi ʻana o ka microwave i hoʻohana pinepine ʻia i nā ʻōnaehana radar, nā kamaʻilio ukali, a me nā noi ʻepekema ʻē aʻe. Pili kēia hoʻololi i ka hana ʻana i nā hōʻailona ma nā alapine kiʻekiʻe loa (microwaves) no nā kumu like ʻole, e like me ka hoʻomaikaʻi ʻana i ka hoʻonā a me ka hōʻemi ʻana i nā mea hoʻopilikia.
Nā noi hana hōʻailona Analog
He nui nā noi o ka hana ʻana i nā hōʻailona analog i ke ola o kēlā me kēia lā a me nā ʻoihana:
1. Kelepona
ʻO ka hana ʻana i nā hōʻailona analog ke kumu o nā ʻōnaehana kelepona e like me ka lekiō, ke kīwī, a me nā kelepona. ʻO ka modulation hōʻailona a me ka demodulation e hiki ai ke hoʻoili i ka ʻike ma nā wahi mamao me ka ʻole o ka nalowale nui o ka ʻikepili.
2. ʻŌnaehana Leo a me Mele
I loko o nā ʻōnaehana leo, hoʻohana ʻia ka hoʻonui ʻana i ka hōʻailona a me ke kānana ʻana e hoʻomaikaʻi i ka maikaʻi o ke kani. ʻO nā hopena e like me ka hoʻemi ʻana i ka walaʻau a me ka hoʻopau ʻana i ke kani e hilinaʻi pū kekahi i nā ʻano hana hōʻailona analog.
3. Lapaʻau
I loko o ka mālama ola kino, hoʻohana ʻia nā hōʻailona analog i nā mea hana lapaʻau like ʻole e like me nā electrocardiograms (ECG), electroencephalograms (EEG), a me nā mea hana diagnostic ʻē aʻe. Kōkua ka hana hōʻailona i ka nānā pololei ʻana a me ka wehewehe ʻana i ka ʻikepili lapaʻau.
4. ʻOihana Kaʻa
I ka ʻoihana kaʻa, hoʻohana ʻia nā hōʻailona analog i nā mea ʻike kaʻa e nānā ana i nā kūlana like ʻole e like me ka wikiwiki, ke kaomi o nā kaila, a me nā palena o ka ʻenekini. ʻO ka hana ʻana i kēia mau hōʻailona e ʻae ai i nā ʻōnaehana hoʻomalu pane a maikaʻi hoʻi.
5. ʻIke Mamao
He kuleana koʻikoʻi ka hana ʻana i nā hōʻailona analog i ka ʻike mamao, kahi e pili ana i ka hōʻiliʻili ʻana a me ka nānā ʻana i ka ʻikepili mai nā kumu e like me nā satelite a me nā mokulele no ka meteorological, ka palapala ʻāina, a me nā kumu kaiapuni.
Nā Pilikia i ka Hana Hana Hōʻailona Analog
1. Walaʻau a me ke Keakea:
He mea maʻalahi loa nā hōʻailona analog i ka walaʻau a me ke komo ʻana, hiki ke hoʻopilikia i ko lākou maikaʻi a me ka pololei. He pilikia nui ka wehe ʻana i ka walaʻau me ka ʻole o ka luku ʻana i ka hōʻailona mua.
2. Nā Palena o ka Lako Paʻa:
ʻO nā ʻāpana uila i hoʻohana ʻia i ka hana hōʻailona analog, e like me nā amplifiers a me nā kānana, he mau palena ko lākou e hiki ke hoʻopilikia i ka hana.
3. Pololei a me ka Hoʻoponopono ʻana:
Pono e hoʻoponopono pono ʻia nā lako hana hōʻailona e hōʻoia i nā hopena pololei a hilinaʻi hoʻi. Pono pinepine kēia i nā ʻenehana loea a me nā kumukūʻai koʻikoʻi.
4. Ka Paʻakikī o ka Hoʻolālā:
ʻO ka hoʻolālā ʻana i nā ʻōnaehana hana hōʻailona analog paʻakikī e pono ai nā mākau kiʻekiʻe ma ka ʻenekinia uila a me ka hoʻomaopopo hohonu ʻana i ke kumumanaʻo hōʻailona.
5. Ka Pono o ka Ikehu:
Pono nā noi he nui, ʻoiai nā mea i kaupalena ʻia e ke kino, e like me nā mea ʻike uea ʻole, i nā ʻano hana hōʻailona mālama pono i ka ikehu.
Ka hopena
ʻO ka hana ʻana i nā hōʻailona analog kahi mea nui i nā ʻenehana he nui a mākou e hoʻohana ai i kēlā me kēia lā. Mai nā kelepona a hiki i nā ʻōnaehana lapaʻau, he kuleana koʻikoʻi nā ʻano hana hana hōʻailona analog i ka hōʻoia ʻana e hiki ke hana ʻia a loaʻa pololei a me ka maikaʻi o ka ʻike. ʻOiai nā pilikia he nui, ke hoʻomau nei ka holomua ʻenehana i ka hoʻomohala ʻana i nā mea hana hou a me nā ʻano hana e hoʻomaikaʻi ai i kēia mau hiki ke hana hōʻailona.
Me ka hoʻomaopopo maikaʻi ʻana i nā kumumanaʻo kumu, nā ʻano hana koʻikoʻi, a me kā lākou mau noi pono, hiki iā mākou ke hoʻomau i ka hana hou a hoʻomaikaʻi i ke kahua o ka hana hōʻailona analog no nā pono paʻakikī a like ʻole i ka wā e hiki mai ana.
