    Hoʻohālike Pūnaehana Kūkākūkā

    Ka manawa hoʻouna: Nov-21-2024

    1. Hoʻokaʻawale ʻia e ka lawelawe kamaʻilio

    E like me nā ʻano lawelawe kamaʻilio like ʻole, hiki ke hoʻokaʻawale ʻia nā ʻōnaehana kamaʻilio i nā ʻōnaehana kelepona kelepona, nā ʻōnaehana kelepona, nā ʻōnaehana ʻikepili, nā ʻōnaehana kiʻi kiʻi, a me nā mea ʻē aʻe. hoʻouna pinepine ʻia ma o ke kelepona kelepona lehulehu, e like me ke kelepona kelepona a me nā kamaʻilio ʻikepili lōʻihi hiki ke hoʻouna ʻia ma o ke ala kelepona. ʻO ka ʻoihana hoʻohui pūnaewele kamaʻilio kikohoʻe kūpono no ka lawe ʻana i ka ʻike o nā ʻano lawelawe like ʻole.

    2. Hoʻonohonoho ʻia e ke ʻano modulation

    E like me ka hoʻololi ʻana o ka hōʻailona i hoʻouna ʻia i ke kahawai a ʻaʻole paha, hiki ke hoʻokaʻawale ʻia ka ʻōnaehana kamaʻilio i ka ʻōnaehana hoʻouna baseband a me ka ʻōnaehana hoʻouna bandpass. ʻO ka hoʻouna ʻana i ka baseband ka hoʻouna pololei ʻana i nā hōʻailona unmodulated, e like me ke kelepona kūloko, hoʻolaha kelepona; ʻO ka hoʻouna ʻana o Bandpass kahi huaʻōlelo maʻamau no ka hoʻololi ʻana o nā hōʻailona like ʻole. Nui nā ʻano hana modulation, a ʻo ka Papa 1-1 ka papa inoa o kekahi mau ʻano hoʻololi maʻamau.

    3. Hoʻohālikelike e like me nā hiʻohiʻona hōʻailona

    Wahi a ke ala hoʻouna he hōʻailona analog a i ʻole ka hōʻailona kikohoʻe, ua māhele ʻia ka ʻōnaehana kamaʻilio i ka ʻōnaehana kamaʻilio analog a me ka ʻōnaehana kamaʻilio digital.

    4, e like me ka hoʻokaʻawale ʻana o ka medium transmission

    Wahi a ka media transmission, hiki ke hoʻokaʻawale ʻia ka ʻōnaehana kamaʻilio i ka ʻōnaehana kelepona a me ka ʻōnaehana kelepona. ʻO ke kamaʻilio uea ka hoʻohana ʻana i ka uea (e like me ke uea hāmama ma luna, ke kaula coaxial, ka fiber optical, waveguide, a me nā mea ʻē aʻe) ma ke ʻano he ala hoʻouna e hoʻopau ai i ke kamaʻilio, e like me ke kelepona kūlanakauhale, ke kelepona TV, ke kelepona submarine. Ke hilinaʻi nei ke kamaʻilio uila i ka hoʻolaha ʻana o ka nalu electromagnetic ma ke ākea e hoʻokō ai i ke kumu o ka hoʻouna ʻana i ka ʻike, e like me ka hoʻolaha ʻana o ka ionospheric hawewe pōkole, ka hoʻolaha ʻana o ka microwave line-of-sight propagation, satellite relay a pēlā aku.

    5, e like me ka papa hana hui

    E like me ke alapine hana a i ʻole ka lōʻihi o ka hawewe o nā mea kamaʻilio, ua māhele ʻia i ke kamaʻilio nalu lōʻihi, ke kamaʻilio nalu waena, ke kamaʻilio nalu pōkole, ke kamaʻilio infrared mamao a pēlā aku.

    6, e like me ka hōʻailona multiplexing classification

    ʻEkolu mau ʻano multiplexing maʻamau no ka hoʻouna ʻana i nā hōʻailona multiplex, ʻo ia hoʻi ka hoʻokaʻawale ʻana i ka frequency division multiplexing, ka manawa māhele multiplexing a me ka code division multiplexing. ʻO ka hoʻokaʻawale ʻana o ka mahele pinepine ʻo ia ka hana ʻana i nā hōʻailona like ʻole e noho i nā pae alapine like ʻole ma o ka hoʻololi ʻana i ka spectrum. Hoʻohana ʻia ka hoʻololi ʻana i ka pulse e hana i nā hōʻailona like ʻole e noho i nā manawa manawa like ʻole. ʻO ka code division multiplexing ka hoʻohana ʻana i ka hoʻopili ʻana i ka orthogonal e lawe i nā hōʻailona like ʻole. Hoʻohana ʻia ka hoʻokaʻawale ʻana i ka pinepine ma ke kamaʻilio analog kuʻuna. Me ka hoʻomohala ʻana o ke kamaʻilio kikohoʻe, hoʻohana nui ʻia ka hoʻonui ʻana i ka manawa. Hoʻohana ʻia ka code division multiplexing i ka launa pū ʻana o ka lewa a me ka ʻōnaehana kamaʻilio kelepona. Eia kekahi, aia nā hawewe mahele multiplexing, space division multiplexing.
