本文从数学理论推导入手,得出传统的AM发射机实现DRM标准数字式调制的数学原理和实现步骤,并在此基础上,对进行DRM改造过程中的几个关键问题进行了探讨。
In this paper, we begin with the introduction of mathematical theory, and come to the mathematical principles and implementation steps of the traditional AM transmitter to realize DRM standard digital modulation. On this basis, we discuss some key issues in the process of DRM transformation.
