通信原理课程设计：语音信号基带通信传输系统仿真基于DPCM编码和循环码 (Communication Theory Course Design: speech signal base-band telecommunication transmission system simulation Based on DPCM coding and cyclic codes)

基于ANSYS APDL二次开发的航电设备的动力学扫频分析，载荷输入条件为交越频率以下为恒定位移，交越频率以上为恒定加速度。我将加速度输入转换为位移输入，将位移和加速度两段输入载荷统一按照位移载荷输入，将位移存入表数组，利用ANSYS APDL自动将扫频范围内的位移载荷存入表数组，并循环加载计算，实现了该工程结构的正弦扫频振动分析。(Kinetic sweep analysis, load input conditions of secondary development based on ANSYS APDL avionics for the crossover frequency less constant displacement, above the crossover frequency is constant acceleration. I will convert the input displacement input acceleration, displacement and acceleration loads unity in accordance with the displacement of the two input load input, the displacement of the array into the table using ANSYS APDL automatically load displacement within the sweep range of the array into the table, and cyclic loading calculated to achieve a swept sine vibration of the project structure.)
