Baseband passband：基頻
基頻
基頻（英語：baseband）是頻率範圍非常窄的訊號，也就是說振幅譜僅在原點（f=0）附近才是非零的，其他頻率幾乎可以忽略。...在電信與訊號處理中，基頻訊號是未經載波調變 ...。其他文章還包含有：「5.1Basebandvs.PassbandCommunicationSystems」、「Baseband」、「Basebandvs.PassbandCommunicationSystems」、「DifferenceBetweenBasebandandPassband」、「PassbandvsBasebandBandwidth」、「PassbandWirelessCommunicationI...
