Alapine (frequency) haiahū kūmau

Alapine (frequency) - keia mea i kekahi o nā 'ano o ka ikaika hawewe o na oscillations o ka physical nui a me ka mahalo i kona kaulana nui. Ma ke kālaikūlohea, ua nui na ano o ka kuekueni o kekahi ano, no ka laʻana, fluctuations ma ka electromagnetic a kula. Ma waho aʻeo ka noho'na makaainana i ulu electromagnetic a ale o maoli me Kinohi, ma laila nō fluctuations, ka hanana a i ua hāʻawiʻia ma ka makemake o ke kanaka, e hoʻoponopono i ka ho'ākāka 'ia i kupu mai, mai na pono o ke kanaka ha awina pilikia. Loa pinepine ma ka mea o ka oscillatory keʻano o ka hanaʻana ka hoʻoponopono 'kumuhana o ka ikehu hoolilo a me / ai' ike, oa Ua mea ma ka palapala, Radio, kīwī a me ka hana, etc.

Ke kaʻina hana o ka pū i hiki 'ike mai nā' ka makaukau ana o ka like ikehu kahua a me kona modulation o ka pono keia mau mea neaiaea, a ua hoʻomakaʻia i ka lēkio leo lawe alapine (frequency) me ia i ho'ākāka 'aiao cia - ikaika hawewe a me ka alapine (frequency). Ke aiao mua ka hapaʻauhau i ka ikehu kahua, a hoʻoholo i ka EYI loihi, a me ka lua - ka addressee. Ma kēia kahua mākou i wale lawe neaiaea, lawelawe i ke kūlana o ka "lawe"ʻikepili.

Ka maʻiʻo 'ike o ka ikehu ke kahua ua hoʻolauna i loko o ka hōʻailona ma ka AYEIE loli kekahi o kona kiko'î. I hana, hoʻohana likeʻole nā koho e hoʻololi i ke kahua kiko'î a - a ua kapaʻia kēia kaʻina modulation lawe alapine (frequency). Ma keia hihia, no ka loli ua noi lawe, a me ka ikaika hawewe o ka lawe alapine (frequency) haiahū kūmau. Ma ke kahua o ka lilo i ka Radio pinepine hoʻohana ikaika hawewe modulation, ma ka ike ua hookomoia ma ka ikaika hawewe o ka lawe neaiaea. Nā loli i ka lawe ikaika hawewe pololei
Information hai Analog maika i. Ke consumer loaa i ka peahi ana
i ke kumu o ka lawe alapine (frequency), a laila, allocates kakauiaʻi maloko demodulator
'ike. Ma haʻahaʻa nä alapine, i ka huahelu i ka wa pokole-nalu, hoʻohana ikaika hawewe wale modulation. Kona papa kuhikuhiE keakea o ka loli ma ka ikaika hawewe o ka lawe alapine, ma muli o ia i ka hōʻailona - halulu hiʻohiʻona, nui ka anakahi o ka pono o ka palapala Kanal ua hoemiia.

Nō hoʻi ka ikaika hawewe modulation, no ka pū i hiki ike hoʻohana a me ke alapine (frequency) i i ke alapine (frequency) haiahū kūmau ua hoʻohana 'ia. Ka lanakila o ke alapine (frequency)
modulation - kiekie ae walaʻau e hoʻonele, no laila, 'oihana
Palapala nenoai e hoʻohana wale nō chastotnomodulirovannye lepa. Kumu o ke noi ana o ka lepa a - VHF Hou, kīwī, kūikawā kamailio.

Haiahū kūmau - ka mea i kā mākou lawe alapine loli pili i ka awelika o kona waiwai. I ka pae ana o ka alapine-pē lawe oscillation hilinaʻi nui ma ka ikaika hawewe o ka pono keia mau mea neaiaea a me kona ikaika hawewe aʻole ĸokoĸa ana nä pane, no ia mea, e pili ana kumupaʻa mea nui kiʻekiʻe ma mua o initially.

ka lawe alapine (frequency) i ke alapine (frequency) modulation maalea i kapaia modulators maika i. Lākou kūlana ma ka EYI o ka Radio mau lepa a - ka mīkini hana wāwahie hooponopono lēkio leo lawe alapine (frequency). Hoʻoholo i ke alapine (frequency) haiahū kūmau
olelo no ka laula o ka bandwidth o nā ka lēkio leo a me ka pa alima.

Mai ka papa kuhikuhiE koi no ka palapala Kanal - paha hou pololei EYI o ka palapala neaiaea, pono ia ma ka liʻiliʻi loa o ka bandwidth o ka hoʻokomo o-ia auoiaea i puhi ai o ka pa alima a me ka lēkio leo papalua ka waiwai o ka palapala neaiaea bandwidth. Eia naʻe, 'aneʻi mākou i e nana i ke "gula, pōʻele maila", no ka mea, mea, lalau mai haiahū kūmau ma kaʻaoʻao lēkio leo hiki ke pili me ka parasitic oscillations, kena ae la ia e extraneous pāhawewe nā pickups, a me ka hanaia'na o deliberate 'ākeʻakeʻa, e like me kekahiʻaoʻao o ke kanaka me ka ai me ka ei o ka neaiaea - ke kapu o ka bandwidth. I hookuu olelo o ka pilina ma waena o ka papa kuhikuhi
Haiahū kūmau ano - a me ka pono ?? poʻe laula o ka pae o ka pū i hiki neaiaea.

Inā ka modulation indexes i nui kumukuai, nā mea kiko'î, a
wehewehe aku ma ke alapine (frequency) haiahū kūmau, i ka hola o ka ia nui. Ke haiahū kūmau ana i loko o nä anakahi alapine Hz.
