通信网络
说明: 在n个城市建设通信网络,只需架设n-1条线路即可至少包含10个城市,城市数n由键盘录入,城市坐标由随机函数产生小于100的整数(In the construction of communication network in n cities, only n-1 lines are needed to include at least 10 cities. The number of cities n is input by keyboard, and the coordinates of cities are generated by random functions into integers less than 100.)

IIR
使用matlab实现设计IIR滤波器:冲激不变法、双线性变换法
设计一个巴特沃思低通滤波器,其技术指标为:3dB带宽为,阻带截止频率为,阻带衰减大于30dB,采样间隔T=10us。
1)用冲激响应不变法
2)用双线性变换法设计
3)用FIR的矩形窗函数设计
二、用双线性变换法分别设计低通、高通、带通、带阻四种滤波器。模拟滤波器带原型分别为切比雪夫滤波器和椭圆滤波器,采样率Fs=20kHz,指标如下:
1)低通:通带0~4 kHz,阻带5 kHz,通带衰减Rp=0.5dB,阻带衰减As=10dB。
2)高通:阻带0~4 kHz,通带5 kHz,通带衰减Rp=0.5dB,阻带衰减As=10dB。
3)带通:通带2kHz~4 kHz,阻带0~1.5 kHz,4.5kHz以上,通带衰减Rp=0.5dB,阻带衰减As=10dB。
4)带阻:阻带2kHz~4 kHz,通带0~1.5 kHz,4.5kHz以上,通带衰减Rp=0.5dB,阻带衰减As=10dB。(Using MATLAB to implement the design of IIR filters: impulse invariant and bilinear transformation)
