Mfundo ya wailesi

Mu 1887 godu Genrih Gerts anasonyeza kuti mphamvu mu atomu ungathe kutumizidwa mu mlengalenga mphepo yomwe kudutsa m'mlengalenga za kuwala kumayendera. kupezeka anathandiza kukhazikitsa mfundo wailesi kuti ali lero. Komanso, asayansi atsimikizira kuti mphepo ali mu atomu mu chilengedwe, koma mbali yaikulu - ndi pafupipafupi imene mphamvu zimasiyanasiyana pakati pa minda ya magetsi ndi maginito. Pafupipafupi mu hedzi (Hz) chokhudzana ndi timaganiza λ, ndilo mtunda umene wailesi yoweyula akudutsa pa oscillation wina. Choncho, chilinganizo zotsatirazi: λ = C / F (kumene C ndi kuwala kumayendera).

mfundo zochokera pa wailesi kufala kwa mphepo mudziwe kumangopitirizabe. Iwo angathe kupatsira mawu kapena deta yadigito. Kuti zimenezi zitheke, a wailesi ayenera:

- Chipangizo kwa kutolera mfundo mu mbendera magetsi (mwachitsanzo, maikolofoni). tenepa amatchedwa chachikulu pafupipafupi bandi mu ochiritsira osiyanasiyana audio.

- Modulator kulowa zambiri mu bandiwifi chizindikiro pa anasankha wailesi pafupipafupi.

- A chopatsilira mkuzamawu mphamvu ndi chizindikiro chimene amatumiza ku mlongoti ndi.

- The mlongoti wa ndodo electrically conductive cha kutalika ena, umene zimatulutsa mphepo mu atomu.

- chizindikiro mkuzamawu kumbali wolandila.

- demodulator, amene adzatha bwinobwino mfundo oyambirira analandira wailesi chizindikiro.

- Pomaliza, ndi zida kwa kubereka mfundo opatsirana (mwachitsanzo, wokamba).

mfundo wailesi

Mfundo yamakono ya wailesi pathupi pa chiyambi cha m'ma lomaliza. Ngakhale wailesi cholinga makamaka mawu ndi nyimbo. Koma posachedwapa ndi mwayi kugwiritsa ntchito mfundo za kulankhulana wailesi ya kufala kwa deta zina. Mwachitsanzo, monga lemba. Zimenezi zinachititsa kuti atayamba malamulo wanthambo.

Common mawu, nyimbo kapena wanthambo ndi kuti mudziwe kwenikweni ndi encrypted mu zizindikiro phokoso, yodziwika ndi matalikidwe ndi pafupipafupi (Hz). Anthu akhoza kumva mu osiyanasiyana kuchokera 30 Hz pafupifupi 12,000 Hz. osiyanasiyana akutchedwa sipekitiramu phokoso.

The sipekitiramu wailesi pafupipafupi lagawidwa osiyana magulu pafupipafupi. Aliyense wa iwo ali ndi makhalidwe enieni ndi ulemu kwa umuna ndi kuwola mu mlengalenga. Anali yekhayekha monga afotokozera mu tebulo pansipa ntchito mauthenga kuti ntchito osiyanasiyana anapatsidwa.

Lero N'zovuta kulingalira zomwe akanachititsa anthu kulankhulana wailesi, zomwe wapeza ntchito zake zipangizo zambiri zamakono. Mwachitsanzo, mfundo za wailesi ndi televizioni ntchito mafoni, kiyibodi, GPRS, Wi-Fi, opanda zingwe Intaneti kompyuta ndi zina zotero.
