随着网络带宽的越来越大以及嵌入式技术和嵌入式设备的日益发展成熟,过去的很
多设备如今变成了可管理的网络设备,它们不仅嵌入了操作系统和拥有自己的IP 地址,而
且还通过嵌入web 形式的网络代理端以方便用户的控制和管理。本文通过在arm920t 的开发
板上移植BOA(一个开源的web server),并嵌入到接入网络设备当中以实现对其进行web
化的控制和管理。(With increasing network bandwidth and embedded technology and the increasing development of sophisticated embedded devices, over the past many devices now become manageable network equipment, which not only embedded operating system and has its own IP address, and through web forms embedded in the network proxy client to facilitate the user' s control and management. In this paper, the development board in arm920t transplant BOA (an open source web server), and embedded in the access network equipment for them to achieve their web based control and management.)

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)
