基于通用集成运算放大器，利用MASON公式设计了一个多功能二阶通用滤波器，能同时或分别实现低通、高通和带通滤波，也能设计成一个正交振荡器。电路的极点频率和品质因数能够独立、精确地调节。电路使用4个集成运放、2个电容和11个电阻，所有集成运放的反相端虚地。利用计算机仿真电路的通用滤波功能、极点频率和品质因数的 ...

这是最难的一个程序了，算法是运筹学里的branch band的集装箱问题的最优动态规划解法，当年我的头都大了才实现的，绝得数学加实践的程序

ALTERA NIOS处理器实验，QUARTUS下用VHDL编译成处理器，自动band跟踪小程序

computes the eigenvalues of a symmetric tridiagonal * matrix T. The user may ask for all eigenvalues, all eigenvalues in the half-open interval (VL, VU], or the IL-th through IU-th eigenvalues.

This m-file simulates MPSK (theoretical and simulated) with Gray coding This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel ...

In this paper, we provide an overview of the security concerns introduced by wireless LANs, current approaches to wireless LAN security, their limitations, and the weaknesses of various “band aid” security solutions. We conclude by describing how the ReefEdge Connect System provides a comprehensiv ...
