惯性导航系统误差传播特性分析，北航惯性导航基础大作业，内含matlab程序代码(Inertial navigation system error propagation characteristics analysis, Northern Inertial Navigation foundation work, containing matlab code)

脉冲编码调制（PCM）是数字通信的编码方式之一，在通信系统中完成将语音信号数字化的功能。PCM的实现主要包括三个步骤：抽样、量化、编码，分别完成时间上离散、幅度上离散及量化信号的二进制表示。(Pulse code modulation (PCM) is one of the encoding of digital communications, in a communication system will complete the function of digital speech signals. The realization of the PCM mainly includes three steps: sampling, quantization and coding, completed on the discrete time, the amplitude of discrete and quantify the binary representation of signals.)

采用双闭环控制的单相逆变器控制结构，simulink 仿真结果正确(PI control，realised the unity power factor)

DFS CODE Depth-first search algorithm Matlab source this procedure site collected from abroad, is the standard depth-first search algorithm, can be achieved and the detection circuit node traversal functions, details see the original English Notes I added this procedure randomness, that is, bifurcation encountered when a randomly selected node, become a random depth-first search algorithm
