说明：  昨天刚刚写好的dsb-sc信号生成与解调程序，用离散（dsp）的方法生成DSB信号，载波频率为150khz,音频是500hz和2000hz的混合音，加入SNR=1DB的噪声，用正交解调实现解调，画出解调前后的频谱图，欢迎共同学习，进步。(yesterday just finished the dsb- sc signal generation and demodulation process, discrete (dsp), the signal generated DSB, the carrier frequency of 150kHz, audio is 500Hz and 2000hz mixed audition to join SNR = 1DB of noise, with quadrature demodulator to achieve demodulation, paint around the demodulation spectrum welcome to learn together and progress.)

MATLAB 图像处理命令，在二进制图像中利用 lookup 表进行边沿操作(MATLAB image processing orders, in a binary image using the lookup table by using the edge operator )

说明：  wavefront Zernike calculation

From the partial fraction expansion of H(z) we can find a, b

主要是针对面向对象设计中的模块应用，详细见英文说明。。。(NCMGUI Master GUI for Numerical Computing with MATLAB. NCMGUI provides an interface to nineteen of the graphical demostrations from "Numerical Computing with MATLAB". Click on any graphic to access the underlying function.)

详细描述了pid各项参数的调试过程，主要是用于电机控制中。(A detailed description of the commissioning process pid parameters, mainly for motor control.)
