Wailesi ya FM yalowa m'miyoyo ya anthu ambiri ndipo ndi njira yomwe imagwiritsidwa ntchito kwambiri pakuwulutsa. Iwo amaulutsa maprogramu amitundumitundu a zokuzira mawu a mawailesi kuti abweretsere anthu chisangalalo cha moyo. Komabe, kodi mukudziwa mmene siteshoni ya wailesi imajambulira mawu amenewa ndi kuchititsa kuti pulogalamuyo izimveka pa wailesi? Nkhaniyi ikuuzani yankho kudzera.
Kodi FM Radio Station ndi chiyani?
Wailesi ya FM ndi gulu la zida zomwe zili ndi chimodzi kapena zingapo Zida zoulutsira mawayilesi a FM. Idzaphimba chizindikiro cha wailesi kudera lamalo kuti akwaniritse cholinga cha kulankhulana kwamawu ndi zida za wogwiritsa ntchito. Pali mitundu yambiri yamawayilesi a FM, monga wailesi yakumzinda, wailesi yam'deralo, kuyendetsa ntchito, wailesi yapayekha, ndi zina zambiri. Nthawi zambiri, phukusi lathunthu la wayilesi ya FM lidzakhala ndi izi:
- Wofalitsa wa FM
- Katswiri wa FM dipole antenna
- 20m coaxial chingwe chokhala ndi zolumikizira
- Chosakaniza cha 8
- Ma headphone awiri owunika
- Awiri oyang'anira oyankhula
- Purosesa yomvera
- Maikolofoni awiri
- Maikolofoni awiri oyimirira
- Chophimba cha maikolofoni awiri BOP
- Zina zofunika zowonjezera
Kupyolera mu zipangizozi, phokosolo limasinthidwa pang'onopang'ono, kufalikira, ndipo pamapeto pake kulandiridwa ndi kusewera ndi wailesi ya wogwiritsa ntchito. Pazida izi, ma transmitter a FM, Mlongoti wa FM, chingwe ndi mzere womvera ndizofunikira, ndipo wailesi ya wailesi sangakhale popanda iwo. Zida zina ziyenera kusankha ngati ziwonjezeko ku wayilesi yowulutsira mawu malinga ndi momwe zilili.
Kodi amagwirira ntchito limodzi bwanji?
Pazida zomwe tazitchula pamwambapa, ma transmitter a FM ndiye chida chofunikira kwambiri pamagetsi, ndipo zida zina zamagetsi zimagwira ntchito mozungulira. Chifukwa chowulutsira mawayilesi a FM sichimangokhala chida chamagetsi choulutsira mawayilesi, komanso chifukwa cha izi, mawayilesi owulutsa a FM amawunikiranso momwe mawayilesi amawulutsira pamlingo waukulu.
Kugwira Ntchito pafupipafupi
Ma frequency ogwirira ntchito a transmitter amatsimikizira kuchuluka kwa wayilesi. Mwachitsanzo, ngati transmitter imatumiza ma frequency a wayilesi pa 89.5 MHz, ma frequency a wayilesi ndi 89.5mhz. Malingana ngati wailesiyo ikasinthidwa kukhala 89.5mhz, omvera amatha kumvetsera pulogalamu ya wayilesiyo.
Nthawi yomweyo, ma frequency a transmitter ndi osiyana, chifukwa gulu la ma frequency a FM lomwe limaloledwa ndi dziko lililonse ndi losiyana. Mayiko ambiri amagwiritsa ntchito 88.0 MHz ~ 108.0 MHz, pamene Japan amagwiritsa ntchito 76mhz ~ 95.0 MHz frequency band, ndipo mayiko ena ku Eastern Europe amagwiritsa ntchito 65.8 - 74.0 MHz frequency band. Ma frequency ogwiritsira ntchito ma transmitter omwe mumagula amayenera kukwaniritsa ma frequency band omwe amaloledwa m'dziko lanu.
Kugwira Ntchito Mphamvu
Mphamvu ya transmitter imatsimikizira kufalikira kwa wayilesi. Ngakhale kuwulutsa kwawayilesi kumakhudzidwa ndi zinthu zambiri, kuphatikiza mphamvu ya transmitter, kutalika kwa kukhazikitsa kwa mlongoti, kupindula kwa mlongoti, zopinga zozungulira mlongoti, magwiridwe antchito a wolandila FM ndi zina zotero. Komabe, kuphimba kumatha kuyerekezedwa molingana ndi mphamvu ya transmitter. Izi ndiye zotsatira zoyeserera za mainjiniya a fmuser. Pansi pazikhalidwe zina, ma transmitter amphamvu zosiyanasiyana amatha kufikira kuphimba koteroko, komwe kungagwiritsidwe ntchito ngati chothandizira kukuthandizani kusankha mphamvu ya transmitter.
Njira Yogwira Ntchito
Wailesi ya FM simagwira ntchito ndi chipangizo chimodzi chamagetsi. Ngakhale ma transmitter a FM ndiye chida chofunikira kwambiri pamagetsi, chimafunika mgwirizano ndi zida zina zamagetsi kuti amalize zowulutsa wamba.
Choyamba ndi kupanga zinthu zowulutsa - zomwe zimawulutsidwa ndikupanga mawu, kuphatikiza mawu a wolengeza, kapena ogwira nawo ntchito amayika mawu ojambulidwa pamakompyuta. Kwa mawayilesi akatswiri, angafunikenso kugwiritsa ntchito zosakaniza ndi ma processor amawu kuti asinthe ndikuwongolera zomwe zili m'mawuwa kuti apeze zowulutsira bwino.
Ndiye pali kulowetsa kwamawu ndi kutembenuka - mawu osinthidwa ndi okometsedwa amalowetsedwa mu Kutumiza kwa wailesi ya FM kudzera pamzere wamawu. Pogwiritsa ntchito kusinthasintha kwa FM, wotumizira amatembenuza mawu osadziwika kumakina kukhala siginecha yamawu yomwe imatha kuzindikirika ndi makina, ndiye kuti, chizindikiro chamagetsi choyimira mawuwo ndikusintha kwaposachedwa. Ngati transmitter ili ndi ukadaulo wa DSP + DDS, imayimitsa siginecha yamawu ndikuwongolera mtundu wamawu.
Kuwulutsa ndi kulandila ma siginecha a wailesi - Ma transmitter a FM amatumiza ma siginecha amagetsi ku mlongoti, kuwasandutsa ma siginecha a wailesi ndikumafalitsa. Wolandira mkati mwa kuwulutsa kwake, monga wailesi, amalandira mafunde a wailesi kuchokera ku mlongoti ndi kuwasandutsa ma siginecha amagetsi kuti atumizidwe kwa wolandira. Pambuyo pokonza ndi wolandirayo, idzasinthidwa kukhala phokoso ndi kufalikira. Panthawiyi, omvera amatha kumva phokoso la wailesi.
Mukufuna Broadcast wayilesi?
Onani apa, kodi mukufuna kukhazikitsa wayilesi nokha? Kugula zida zoulutsira pawayilesi, mutha kusankha Rohde & Schwarz. Iwo akutsogola m'mabizinesi owulutsa pawailesi. Zogulitsa zawo ndi zapamwamba, koma zimabweretsanso mavuto okwera mtengo. Ngati mulibe bajeti yayikulu chonchi, bwanji osasankha fmuser? Monga katswiri wothandizira zida zowulutsira pawailesi, titha kupereka mawayilesi athunthu ndi yankho ndi mtundu wokhazikika komanso mtengo wotsika. Ngati mukufuna, lemberani.
