The Analysis of Factors Affecting the SNR of DAM Medium Wave Broadcasting Transmitter and Research on Countermeasures
This paper mainly studies the main factors affecting the signal-to-noise ratio of Digital Amplitude Modulation(DAM)medium wave transmitter and the corresponding countermeasures.Firstly,the working principle of digital AM broadcasting and the basic concept of Signal-to-Noise Ratio(SNR)of medium-wave transmitter in DAM are introduced.Secondly,the main factors affecting the SNR of medium-wave transmitter in DAM are analyzed emphatically.Finally,the measures to restrain its influence are put forward,which provides reference for improving the performance of medium-wave transmitter in DAM.
