GMSK
- GMSK是高斯滤波的最小频移键控的简称，基本的工作原理是将基带信号先经过高斯滤波器成形，再进行最小频移键控(MSK)调制。由于成形后的高斯脉冲包络无陡峭边沿，亦无拐点，因此频谱特性优于MSK信号的频谱特性。-GMSK Gaussian filter is the smallest FSK abbreviation, the basic working principle is to base-band signal to pass Gaussian filter shape, and then

- 频率合成技术在现代电子技术中具有重要的地位。在通信、雷达和导航等设备中，它可以作为干扰信号发生器；在测试设备中，可作为标准信号源，因此频率合成器被人们称为许多电子系统的“心脏”。直接数字频率合成（DDS——Digital Direct Frequency Synthesis）技术是一种全新的频率合成方法，是频率合成技术的一次革命。本文主要分析了DDS的基本原理及其输出频谱特点，并采用VHDL语言在FPGA上实现。对于DDS的输出频谱，一个较大的缺点是：输出杂散较大。针对这一缺点本文使用了两个方法
