通过matlab实现从声卡发出不同频率的声波(diffirent frequency sound out)

Power flow studies, commonly known as load flow, form an important part of power system analysis. They are necessary for planning, economic scheduling and control of an existing system as well as planning its future expansion. The problem consists of determining the magnitudes and phase angle of voltages at each bus and active and reactive power flow in each line. In solving power flow problem, the system is assumed to be operating under balanced conditions and a single-phase model is used. Four quantities are assumed at each bus. These are voltage magnitude v, phase angle  , real power P, and reactive power Q.The Newton Raphson method of load flow analysis is an iterative method which approximates the set of non-linear simultaneous equations to a set of linear simultaneous equations using Taylor’s series expansion and the terms are limited to first order approximation.

实现QAM调制解调，分为16QAM、64QAM，包括瑞利信道的仿真程序，可以供初学参考。(Implementation of QAM modulation and demodulation, divided into 16QAM, 64QAM, including Rayleigh channel simulation program, can be reference for beginners.)

这学期开了软件工程工具及其应用这么课，任老师给我们教了matlab程序设计语言，做了课程实验，自己用matlab实现了计算器，发现MATLAB确实是一门很有用得计算机编程语言，它把数值计算和可视化环境集成到一起，非常直观，而且提供了大量的函数，功能强大，工应用范围广泛。 (Opened this semester and its application software engineering tools such class, any teacher taught us matlab programming language, has done a course experiments using matlab realize their own calculators, found that MATLAB is indeed a very useful computer programming language , which the numerical computation and visualization environment for integrated together, very intuitive, but also provides a large number of functions and powerful, the broad scope of application.)
