matlb编写的IIR滤波器程序，按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(IIR filter matlb prepared by the procedure, according to set targets and analog low-pass filter (Butterworth low-pass or low-pass Chebyshev) approximation to the ideal analog low-pass filter, and then through the bilinear transformation method for analog filtering device to digitize, the digital filter.)

this code simulates a 4fuzzy PID cotroller for ball-baem system and 3 other systems.

说明：  有详细的线性规划法源代码，可以用于控制器参数寻优(Detailed linear programming source code, can be used for controller parameters optimization)

实现彩色图象的读取,以及回度图象的读取,及相关的变换(Achieve color image reading, and reading back of the picture, and the associated transformation)

这是利用MATLAB图形用户界面设计技术设计的一个关于基于神经网络的变压器故障诊断系统,全部语言用MATLAB所编,途中还涉及三比值法 无编码法的MATLAB编程程序.(This is using MATLAB graphical user interface design, technical design of a neural network on the basis of the PSA Fault Diagnosis System, all language prepared by using MATLAB, while also involves three ratio method without coding method MATLAB programming procedures.)

用MMSE LMS Wiener-Hopf三种方法补偿QPSK调制信号在非理想信道的源代码(MMSE LMS and Wiener-Hopf solutions to QPSK modulated signal transmitting through non-ideal channel)

数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 (Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.)
