Batun "siginonin ƙarya" a cikinƙara siginar wayar hannu babban ciwon kai ne ga masu amfani da yawa. Bari mu raba wannan matsalar fasaha ta hanyar da ta fi dacewa:
Ka yi tunanin kana ƙoƙarin neman wani a cikin kasuwa mai hayaniya. Ƙara sigina mara inganci kamar dattijo ne mai wahalar ji—ko da yake yana ihu "An ƙara sautin!" ta cikin babban murya, sai ya ƙara duk hayaniyar bango (sautin yankewa, muryoyin hayaniya, da sauransu), wanda hakan ya sa ya fi wahala a ji ainihin muryar da kake buƙata. Amplifier mai inganci, a gefe guda, yana aiki kamar ƙwararren injiniyan sauti, yana ɗaukar mitar da ake buƙata kawai.
Musamman ma, akwai muhimman abubuwa uku na fasaha da ke bayan wannan lamari:
1. Gane Sigina tare da "Daidaicin Laser"
Mai ƙara siginar mai araha yana aiki kamar mutumin da ba ya ganin komai ba tare da tabarau ba—yana kuskuren yin wani motsi don samun ingantaccen sigina. A zahiri, raƙuman lantarki masu ƙarancin mitoci daga injinan iska (0.1–10Hz) ko tsangwama na 50Hz daga layukan wutar lantarki na iya haifar da rashin gaskiya. Masu ƙara siginar wayar salula masu inganci suna amfani da da'irori masu tacewa masu matakai da yawa, galibi "na'urar daukar hoton yatsa" don sigina, don toshe hayaniya.
2. Tsarin "Nunawa Mai Wayo"
Tsarin wayar hannu mai haɓaka hanyar sadarwa ta gaskiya yana amfani da ikon sarrafa riba mai daidaitawa,kama da belun kunne masu soke hayaniya. Lokacin da rabon sigina zuwa hayaniya ya faɗi ƙasa da 15dB, yana kunna tsarin DSP (Digital Signal Processing) don ware sigina masu amfani—kamar mai hakar zinare yana tace yashi. Na'urorin kashe gobara? Sun fi kama da amplifier mai karkacewa, wanda ke tashi tsaye tare da siginar.
3. Garkuwar da Ba a Gani Ba: Tsaron Hasken Radiation
Wasu masu haɓaka siginar wayar salula marasa takardar shaida suna fitar da hasken lantarki sau 10 a iyakar aminci—kamar tanda ta microwave mai ƙofa da ta karye. Kayayyakin da aka amince da su suna amfani da tsarin sarrafa madauri a rufe, suna jagorantar makamashi kamar "bututun ƙarfe" zuwa hasumiyoyin tantanin halitta yayin da suke bin ƙa'idodin tsaro masu tsauri.
Lintratekƙara siginar wayar hannuyana amfani da kayan aiki na zamani kamar LowMasu ƙara Sauti (LNA)kumaMasu ƙara ƙarfin lantarki (PA)don samar da ingantaccen aiki. LNA yana inganta yanayin karɓar karɓa ta hanyar rage hayaniyar gaba, yayin da PA ke ƙara ƙarfin sigina, yana tabbatar da haɗin kai mai haske da kwanciyar hankali. Ta hanyar inganta layi, wayar hannu mai haɓaka hanyar sadarwa tana rage karkacewar sigina kuma tana tace tsangwama yadda ya kamata (kamar hayaniyar lantarki daga wasu tashoshin mita).
An haɗa shi da matattara masu aiki masu ƙarfi, Lintratekƙara siginar wayar hannuyana kawar da tsangwama ga mitar da ba ta da manufa, yana ƙara tsarkin sigina. Ko kuna cikin yankuna masu nisa ko yankunan da ba su da sigina mai rauni, wannanmai haɓaka hanyar sadarwa ta wayar salulayana tabbatar da haɗin wayar hannu mai inganci don sadarwa mai kyau.
Muhimman Abubuwa:
1、 Fasaha ta LNA & PA mai ci gaba don sigina masu ƙarfi.
2、Tace tsangwama mai girma don kiran da ke bayyana a sarari.
3, Ingantaccen layi don rage karkacewa.
4, Matatun aiki masu inganci don mafi girman tsarkin sigina.
Ku kasance tare da ko'ina tare da ingantaccen mai ƙara siginar wayar salula na Lintratek—mafita mafi kyawun hanyar sadarwar ku ta wayar hannu!
Neman ƙiyasin farashi?
