The Analysis and Testing of Acoustic Indicators for DAM 10 kW Medium Wave Transmitter
With the continuous development of information technology,users have higher requirements for medium wave broadcasting services.Harmonic distortion,frequency response,and signal-to-noise ratio are three typical electroacoustic indicators of medium wave transmitters,which are the basic standards for measuring the performance of a transmitter.On the basis of analyzing the working principle of Digital Amplitude Modulation(DAM)10 kW medium wave transmitter,this article tests three electroacoustic indicators of the transmitter,proposes specific testing methods,and clarifies the factors that affect the electroacoustic indicators.
