一、電臺是什么意思
電臺是無線(xian)電(dian)(dian)臺(tai)的(de)簡稱(cheng)。設(she)有(you)無線(xian)電(dian)(dian)發射機、接(jie)收機和天線(xian)等裝置(zhi),用(yong)以發送或接(jie)收無線(xian)電(dian)(dian)信號的(de)場(chang)所。有(you)時也將這些設(she)備(bei)稱(cheng)為電(dian)(dian)臺(tai)。從(cong)應用(yong)角(jiao)度出發可分(fen)為話(hua)音傳(chuan)輸的(de)對(dui)(dui)講電(dian)(dian)臺(tai)(如:對(dui)(dui)講機、車載(zai)臺(tai)等)和數據傳(chuan)輸的(de)數傳(chuan)電(dian)(dian)臺(tai)(如:MDS數傳(chuan)電(dian)(dian)臺(tai))等。
