Pane nzira dzakawanda dzokuteerera mimhanzi nezvimwe zvinyorwa zvehurukuro mumotokari yako kupfuura kare kare, asi vazhinji vavo havanyanyi kutamba zvakanaka nevakuru vakuru vemudiki. Kunze kwekuti motokari yemotokari yako yakauya neine rubatsiro rwekubatsira, zvaunosarudza zvakaisvonaka zvishoma. Ndiko mune-mumotokari yemamodhini FM inogona kubatsira chaizvo sezvo izvozvi zvigadzirwa zvichinyanya kuwedzera rubatsiro rubatsiro kune chero motokari yemotokari, uye vanoita basa iri nani kupfuura iwe wekushambadzira FM inopikisa.
Chii chinonzi In-Car FM Modulator?
Imwe-motokari FM modulator inongova motokari yemavhudhi modulator iyo yakanyatsogadzirirwa kushandiswa mumotokari yemutambo. Mafunguro eRadio-freulator modulator anongowanzogadzirisa zvishandiso izvo zvaive zvakagadzirirwa kuti zvibvumire zvikamu zvekunze zvakagadziriswa kusvika pane terevhizheni uye maharai mahara.
Sezvo mapevhizheni ose uye maharadhi emisha zvakagadzirwa kuti agamuchire RF chete zvigadziro kubva kune antenna, RF modulators zvinowedzera kuwedzera muteereti uye / kana vhidhiyo kumhepo inotakura, iyo inogona kushandiswa neTV setsetse kana kuti musoro wepamusoro sezvainoita yakanga yakagamuchirwa kuburikidza nepamusoro pekuparidzirwa kwemhepo.
The Basics of Broadcasting
Zvose zvinobudiswa terevhizheni nemavhidhiyo, kusanganisira AM uye FM redhiyo , inoshanda zvakafanana nenzira imwe chete. Paredhiyo kana terevhizheni, manzwiro ezwi uye / kana mavhidhiyo anowedzerwa kumhepo inofambisa nharaunda kuburikidza ne frequency modulation (FM) kana amplitude modulation (AM). Analog kuterevhizheni kuparidzirwa kushandiswa kushandisa vestigial sideband modulation, iyo yaiva yerudzi rwema amplitude modulation, uye kuparidzirwa kwemajeri kunoshandisa mhando dzemhando dzakasiyana dzekugadzirisa. Chiratidzo chinoshandiswa chinoshandiswa zvino chinoparadzirwa pamusoro pemhepo (OTA).
Kana motokari inotakura inotorwa neintenna, chiratidzo chacho chinoderedzwa ne hardware mukati meterevhizheni yakagadzirwa kana redhiyo, iyo inoshandiswa iyo inogadzirisa dhiyabhorosi yemutambo wezwi uye / kana vhidhiyo kubva mumagetsi ekutakura. Chiratidzo chacho chinogona kuonekwa paTV kana kutambidzwa paredhiyo.
Kusvikira munguva pfupi ichangobva kupfuura, terevhizheni yakashaya mimwe yev / v inoshandiswa kunze kweiyo antenna hookup, uye mhepo dzakawanda dzemotokari dzinoramba dzichishayiwa chero rudzi rwekubatsira rubatsiro. Kuti zvive nyore kuwirirana kwezvigadzirwa zvakadai seVCRs kuhevhizheni, uye tape mapeki kana CD players kumotokari dzemotokari, RF modulators dzakagadzirwa.
Kunyengera Tuner neCom FM FM Modulator
Mafirimu emotokari uye terevhizheni zvakagadzirirwa kugamuchira hurongwa hunoenda kune rumwe rutivi rwemagetsi emagetsi. Izvo zvakasiyana nenzira iyo magareti nemigwagwa zvinorondedzerwa, asi zvose zviri zviviri "tungai" kune imwe nguva yakawanda kuitira kuti muwane chero nzvimbo yakasimudzwa kana chiteshi. Chaizvoizvo, motokari yemodzimutori yemodhi inoshandisa zvayo kuti "inonyengedza" musoro wechirungu mukutamba zvakare chimwe chinhu kunze kwekutaura kweOTA. Nenzira imwecheteyo, zvinhu zvose kubva kuVCR kusvika kuDVD maidhi nemavhidhiyo emitambo zvinogona kusungirirwa kumasereti eTV asina mazano A / V.
Kuti uite izvi, mota yemotokari yemodhi inofanirwa kusungirirwa pakati pemusoro wemusoro uye antenna. Zviratidzo zvinobva kune antenna zvinodarika modulator uye kusvika mumusoro wechikwata, asi modulator inewo rubatsiro rwekubatsira runogona kushamwaridzana neCD player, iPod, generic MP3 player, kana chero ipi zvayo yemhanzi. Apo chigadzirwa chabudiswa mu modulator nenzira iyo, inonyanya kuita chinhu chimwechete chinoitika paredhiyo redhiyo: inzwi rezwi rinowanikwa kune chiteshi chekutakura, iyo inobva yapfuura ichienda kumusoro wechikwata.
Car FM Modulators uye FM Transmitters
Kunyange zvazvo motokari yemotokari yemotokari uye inotumira zvinhu yakafanana, pane imwe yerinheyo huru munzira iyo musoro wechipiri inogamuchira chiratidzo. Nemhaka yemitemo iyo inokonesa simba revasina kuvharidzirwa nemavhidhiyo, vatori vemotokari dzemotokari vanofanira kunge vane simba rakanyanya. Vane simba zvakakwana kuti vatumidze maziso mashomanana anowanzovaparadzanisa kubva kumotokari antenna, asi zviri nyore kuti chiratidzo ichocho chisina simba chinyimire kunze kune imwe nzvimbo uko pasina "nzvimbo dzakafa" nzvimbo dziri paMF.
Kubva pamotokari yemotokari yemu FM ichipinza simbi zvakananga mumusoro wechikwata, pane mikana shoma yekupindira. Izvi zvinogona kugadziriswa nekupindira, uye kazhinji hazvikwanise kutarisana nehutano hwehutachiona hwebasa rekubatsira, asi iyo inosarudzo yakanaka yezvikwata zvepamusoro izvo zvisingabatsiri zviteshi zvekubatsira.
