摘要
在m序列产生原理的基础上,利用2片74LS194级联及少量门电路,采用手动置数和自启动2种方法设计了2种m序列发生器电路,然后分析比较了2种电路的产生原理.最后分析了实验结果,验证了m序列的均衡性、游程分布特性及移位相加性.电路性能稳定可靠,已作为数字信号源成功应用于通信原理实验中.
Based on the principle of m sequence generation,two pieces of 74LS194 cascaded circuit and a few gate circuit are used to design two m sequence generators by the methods of manual reset and self-running.Then,the generation principles of these two circuits are analyzed and compared.Lastly,experimental results are analyzed and the characteristics of balance,run-length distribution and shift addition are verified.The circuits run stable,and have been used successfully in communication theory experiments as digital signal source.
