7-Tokotaha Sēkita ʻo e CH FM 7 senolo ʻoku ʻave ʻe he letio FM ʻa e AUX ongo ki he tokotaha lea ʻi he kaa PLL

ʻI he ngaahi taʻu kuo hilí, ʻoku tau ʻomi ha ngaahi naunau fakaʻilekitulonika lahi ʻi he kaa, hangē ko e ʻato ʻo e kaá DVD pe headrest DVD player. Ko e peole lahi taha ʻoku nau fie fanongo ki he ongo mei he ʻuluaki amplifier mo e tokotaha lea. ʻOku faʻu ʻetau transmitter fm lelei taha ke fakaleleiʻi ʻaki e palopalema ko ʻeni.

ʻOku faingofua mo vave hono fokotuʻu ʻo e ngaue ʻa e FM transmitter. ʻIkai fie maʻu ha telefoni pe apk. Ko e aux ʻo e ongo ke fakafehokotaki ki hoʻo kaa, ʻokú ne ʻoatu ʻa e fm transmitter lelei tahá, ki 16 senolo ke fili. Naʻa ne fakaʻaongaʻi ʻa e tekinolosia PLL pea ʻikai mole ha ongo. ʻOku ʻi ai ha transmitter ʻe taha ʻoku fufuuʻi ʻe he wireless FM ʻa e ʻenitena ʻi he keipolo malohi. Te tau lava foki ʻo liliu ʻa e palani ki he FM connector ke fakafehokotaki hoʻo ʻenitena ʻuluaki kaa. Ko ha totongi lelei mo maʻamaʻa ia transmitter fanongo ki he tokoni ke ta ha hiva ʻi he kaa.

ʻOku ʻi ai ha wireless ʻe ua ʻi heʻetau sipinga FM-16 ki he maʻuʻanga ivi malohi (12V malohi ʻi he keipolo ʻo e GND). Te tau lava foki ʻo liliu ia ki he USB connector kapau ʻoku ke fie maʻu. ʻE lava ke fokotuʻu ʻetau transmitter FM mo e AUX input ʻi ha faʻahinga ka pe ʻoku ʻi ai ha letio FM, tuʻo lahi hono tokoniʻí he taimí ni, 87.7, 87.9, 88.9, 88.1, 88.2, 88.3, 88.4, 88.5, 88.6, 88.7, 88.8, 88.9, 89.0, 89.1, 89.2, 89.4.

PLL ʻi he FM transmitter: Pelu Fakafuopotopoto e Konga ʻOku Lokaʻí, ʻOku lelei ʻa e PLLs ki he demodulating tuʻo lahi modulation, ʻOku faingofua ke fakakau ʻa e FM ʻi he ICS mo hono ʻomi ha telinga output. fakaʻaongaʻi ʻa e PLL fakatekinolosia FM transmitter te ne lava ʻo ʻave ʻa e ongo lelei taha ki he letio ʻo e kaa mo e tokotaha lea.
