Ukuphuculwa kwesignali ye-Youdaoplaceholder0: Izihluzi zikwanceda ukuphucula ukuhanjiswa kwesignali eziluncedo, ukuqinisekisa ukwamkelwa kwesignali okuzinzileyo nokuchanekileyo kwizixhobo ezifana neenkqubo zokuhambisa kunye neerediyo. Oku KUBALULEKILE ekusebenzeni okuqhelekileyo kwenkqubo yokuhamba ngemoto kunye ne-RADIO.
Uyilo kunye nomgaqo wokusebenza
Izihluzi ze-antenna zeemoto zihlala zenziwe zii-capacitors, ii-inductors kunye nee-resistor. Ngokusebenzisa uphawu lwazo lokudlulisa ii-frequency eziphezulu kunye nokuvala ii-frequency eziphantsi, ziqondisa ii-frequency interference currents eziphezulu emhlabeni okanye kwi-neutral wire, ngaloo ndlela zibonakalisa okanye zifunxa imiqondiso yokuphazamiseka. Ukongeza, isihluzi sinokucinezela ngakumbi ukuphazamiseka kwe-electromagnetic ngeendlela zobugcisa ezifana nokucoca izigaba ezininzi kunye nesekethe yokuhlawula ikhonkco eliphambili .
Isihluzi se-antenna ye-Youdaoplaceholder0 Isixhobo sokucoca i-antenna ye-Automotive sisixhobo esisetyenziswa kwiinkqubo ze-antenna ye-automotive, esimsebenzi waso oyintloko kukucoca imiqondiso engafunekiyo ukuqinisekisa ukuba i-antenna inokufumana kuphela imiqondiso efunekayo. Izihluzi ziphucula umgangatho wesignali efunyenweyo kunye nozinzo lwenkqubo ngokuvumela ngokukhetha ii-frequency ezithile zesignali ukuba zidlule ngelixa zicinezela ezinye ii-frequency .
Iintlobo kunye nemisebenzi yeefilitha ze-antenna zeemoto
Isihluzi se-Youdaoplaceholder0 Low-pass : Sivumela imiqondiso engaphantsi kwe-cut-off frequency ethile ukuba idlule kwaye sivale imiqondiso engaphezulu kwe-frequency.
Isihluzi se-Youdaoplaceholder0 High-pass : Sivimba imiqondiso engaphantsi kwe-cut-off frequency ethile kwaye sivumela imiqondiso engaphezulu kwe-frequency ukuba idlule.
Isihluzi se-Youdaoplaceholder0 Band-pass : Sivumela imiqondiso yebhendi ethile ukuba idlule kwaye sivale imiqondiso yezinye ibhendi.
Isihluzi sebhendi yokumisa i-Youdaoplaceholder0 : Sivala imiqondiso evela kwelinye ibhendi kwaye sivumela imiqondiso evela kwamanye amabhendi ukuba idlule.
Iimeko zesicelo kunye nokubaluleka kwezihluzi ze-antenna zeemoto
Izihluzo ze-antenna zeemoto zisetyenziswa kakhulu kwiinkqubo ezahlukeneyo ze-elektroniki zeemoto, ingakumbi kwi-antenna ze-shark fin zeemoto. Olu yilo alupheleli nje ekuthandeni ubuhle kodwa lukwanciphisa ukumelana nomoya ngokufanelekileyo. Okwangoku, isihluzo esakhelwe ngaphakathi sinokucoca ukuphazamiseka kwe-electromagnetic okungeyomfuneko, ukuqinisekisa ukusebenza okuzinzileyo kwezixhobo zonxibelelwano. Umzekelo, izihluzo zibaluleke kakhulu kwiindawo ezibalulekileyo ezifana neenkqubo zolawulo lweenjini kunye neebhuleki ukuqinisekisa ukuba ezi nkqubo zithembekile ngakumbi kwaye ziphucula ukhuseleko lokuqhuba.
Umgaqo woyilo kunye neeparamitha zobugcisa zeefilitha ze-antenna zezithuthi
Umgaqo woyilo lwee-antenna filters zeemoto usekelwe kwithiyori ye-electromagnetic kunye noyilo lwesekethe, kwaye idla ngokwenziwa zii-capacitors, ii-inductors kunye nee-resistor. Iiparameter zayo eziphambili zobugcisa ziquka i-center frequency, i-cut-off frequency, i-passband bandwidth, i-insertion loss, i-ripple, i-in-band wave, i-in-band standing wave ratio, i-return loss, i-stopband depression degree, i-delay kunye ne-in-band phase linearity, njl. Ezi parameters zidibene zimisela ukusebenza kunye nesiphumo sesihluzi .
