本文叙述了浮动载波调幅的原理和西德德律风根通用电气公司所采用的方法;介绍了西德墓尼黑广播技术研究所,对采用浮动载波调幅的脉宽调制发射机所做的关于节能和传输质量受到的影响的调查;还介绍了在大功率发射机上运行试验的记录。本文还把新的调制技术同单边带技术进行了比较。最后,对采用不同的调制技术的发射机的能量消耗作了对比。
This paper describes the principle of floating carrier amplitude modulation and the method adopted by West Germany Wind Electric General Electric Co., Ltd. introduced the West German tomb of the Black Broadcasting Institute of Technology, the use of floating carrier amplitude modulation pulse width modulation transmitter made on Energy saving and transmission quality affected by the survey; also introduced in high-power transmitters to run the test records. This article also compares new modulation techniques with single-sideband techniques. Finally, the energy consumption of transmitters with different modulation techniques is compared.
