Tub de raigs cat\u00f2dics:<\/strong> \u00c9s un component essencial d'una TV perqu\u00e8 s'encarrega principalment de transmetre de projectar una imatge determinada capturada per l'antena. Els tubs estan conformats per c\u00e0todes, \u00e0nodes, reixetes i filament.\r\nAntena:<\/strong> Est\u00e0 dissenyada especialment per captar el senyal de difusi\u00f3 que viatja per l'aire. Aquest senyal es transmet a trav\u00e9s de la pantalla, des d'on podem veure la reproducci\u00f3 de contingut multim\u00e8dia.\r\nControl o sintonitzador:<\/strong> Treballa alhora amb el microcontrolador, sent l'encarregada de conservar el canal de TV que volem que estigui sincronitzat.\r\nBocina:<\/strong> La seva funci\u00f3 \u00e9s m\u00e9s que \u00f2bvia, ja que s'encarrega de transformar l'energia ac\u00fastica. Una botzina de televisor \u00e9s aquella que genera els defectes sonors.\r\nV\u00eddeo:<\/strong> Tal com ho indica el seu propi nom, aquesta \u00e9s la responsable d'amplificar imatges de v\u00eddeo.\r\nFlyback:<\/strong> El voltatge alt de l'equip que va a l'\u00e0node TRC ser\u00e0 controlat pel Flyback. Tamb\u00e9 \u00e9s indispensable per regular la nitidesa de la pantalla, per\u00f2 a m\u00e9s per administrar la brillantor i focus en pantalla.\r\nFont d'alimentaci\u00f3:<\/strong> Est\u00e0 encarregat d'alimentar altres dispositius dins del mateix televisor com ara jungla, microcontrolador i \u00e0udio.\r\nMicrocontrolador:<\/strong> Ja hi hem fet refer\u00e8ncia i no \u00e9s m\u00e9s que el cervell de l'aparell o televisor. B\u00e0sicament, s'encarrega d'executar qualsevol ordre de l'usuari des del comandament a dist\u00e0ncia, vigila el funcionament correcte de la resta del sistema i apaga el dispositiu quan detecta un mal funcionament.\r\n\u00c0udio:<\/strong> Aqu\u00ed \u00e9s on s'amplifica el so, el senyal del qual \u00e9s enviat als altparlants o botzines per a la seva reproducci\u00f3.\r\nYugo:<\/strong> La seva funci\u00f3 principal \u00e9s la construcci\u00f3 exacta de la imatge, mitjan\u00e7ant una reflexi\u00f3 vertical i horitzontal de cadascun dels electrons.\r\nJungla:<\/strong> \u00c9s un dels components m\u00e9s importants, ja que est\u00e0 constitu\u00eft al costat del microprocessador. Quina funci\u00f3 t\u00e9? Processar altres elements com \u00e0udio, v\u00eddeo i el sincronisme vertical i horitzontal.<\/span><\/pre>\n
