matlab program for FDTD 3D

The attached source code is the implemenation of acoustic echo canceller and noise reduction.

its a c program for assembler

呵呵,第一次来很多东西不懂 还请多多指教啊! 几个编的简单的FFT和滤波器设计 希望能有点用(Oh, the first to understand a lot of things you will also enlighten ah! several series of simple and FFT filter design with a little hope)

基于matlab将某个灰度值范围内的图像表现的更加突出，形成更好的对比。(Matlab will be a gray value within the image is more prominent, forming a better contrast.)

Book about neural networks

本手册是根据国内最著名的天线专家、教授的最新研究与工程设计成果并汇集了国际上的最新资料精心编撰而成的宏篇巨著，是目前国内第一本全面论述天线工程最系统、最完整的工具书。全书共分四篇29章。第一篇为天线基础，介绍了天线的基本参数、基本原理、基本理论和基本分析方法，为读者阅读后续各章 打下坚实基础；第二篇为天线设计，是全书的核心，介绍各类天线的工作原理和设计方法，可供使用的设计公式、图表和具体数据；第三篇概述天线在通信、雷达、导航、遥测、测向等军民方面的应用，还介绍了特殊用途的天线，如载体天线、圆极化天线、毫米波天线等；第四篇介绍了与天线相关的论题，如天线的测量、天线散射载面、天线罩等。(This manual is based on the latest research and engineering achievements of the most famous antenna experts, professors and brings together the latest information on carefully compiled international macro magnum opus, is the first comprehensive discussion of the antenna construction most systematic complete tool. 29 book is divided into four chapters. The first is the antenna base, introduces the basic parameters of the antenna, the basic principles, basic theory and analysis methods for the following chapters the reader Lay a solid foundation The second is an antenna design is the core of the book, describes various types of antennas working principle and design methods, design formulas available, charts and specific data an overview of the third antenna in communication, radar, navigation , telemetry, military and civilian aspects of the application DF et al., also describes the antennas for special purposes, such as carrier antenna, a circularly polarized antenna, the millimet)

现有一个信号：x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的： 低通滤波器，滤除cos(2*π*n/3) 的成分，即想保留的成分为1+cos(π*n/4) 高通滤波器，滤除1+cos(π*n/4) 的成分，即想保留的成分为cos(2*π*n/3) 带通滤波器，滤除1+cos(2*π*n/3) 的成分，即想保留的成分为cos(π*n/4) 带阻滤波器，滤除cos(π*n/4) 的成分，即想保留的成分为1+cos(2*π*n/3) 1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器；画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。 (an existing signal : x (n) = a cos (* n/4) cos (2** n/3) design and digital filter to achieve the following objectives : low-pass filter, filter cos (2** n/3) the ingredients that want to retain an element of a cos (* n/4) high-pass filter, a filter cos (* n/4) components, namely to retain the element of cos (2** n/3) band-pass filter , a filter cos (2** n/3) components, namely to retain the element of cos (* n/4) band stop filter, the filter cos (* n/4) components, namely to retain the ingredients for a cos ( 2** n/3) 1. MATLAB order butterord except for the band Filter, using the order of the filter design butter; paint Filter magnitude and phase frequency of the corresponding filter system function H (z).)
