q730是模拟低通转换为数字低通.q731是切比雪夫滤波器设计，q732椭圆带通数字滤波器的设计，其中用的是ellipord函数(q730 is converted to analog low-pass digital low-pass. q731 is a Chebyshev filter design, q732 elliptical band-pass digital filter design, which is used in a function ellipord)

本程序是matlab编程，采用了N-R算法中的极坐标法(This program is matlab programming, NR algorithm using polar coordinates)

案例设计源程序，matlab动态创建控件，有函数有界面的设计(Case design source, matlab dynamically created controls, there are functions with interface design)

伯德图的绘制程序，一种特殊的matlab作图方式，多多交流吧(Bode diagram drawing program, a special matlab plotting way more exchanges)

说明：  用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱(Simulink tools with the code (S-Function mode), resulting in a single-path Rayleigh Road, the Doppler spectrum for the classical spectrum)
