dell latitude d820 notebook Schmatices 戴尔笔记本原理图(dell latitude d820 notebook Schmatices Dell laptop schematic diagram)

资料很重要，描述高频线路中的应用。主要是放大电路，实验步骤等等。(The item is very important, describe the application of high-frequency lines. The main amplifying circuit, the experimental procedure.)

已知：信号中心波长为2,天线阵元的间距为1米,快拍数为2000，空中有四个 源信号,假设它们的频率 四个源信号的方向分别为： 求： 1）在不加入噪声的情况下,观察并计算协方差矩阵特征值,并对它的特点 加以说明 2）分别采用MUSIC算法,CAPON算法, ESPRIT算法在下面四种情况下，对 上述四个信号源的波达方向进行估计,并画出它们的空间谱图； ①在不加入噪声的情况下, ②在加入高斯白噪声的情况下,假设信噪比为10dB 3）在信噪比变化范围为-20dB~+20dB时，分别采用MUSIC算法,CAPON算 法, ESPRIT算法，对上述四个信号源的波达方向进行估计,并画出波达方 向估计误差,随着信噪比变化的曲线图(即横轴为信噪比,纵轴为误差值)()

一篇TURBO 均衡的博士论文，非常有价值(A the TURBO balanced the doctoral thesis, very valuable)

ASM Code for calculator using AVR

用于全国电子设计大赛 备赛资料，ment of real-time displaying the position coord(The purpose of the design is to get a more precise hand-written drawing board. We connect the copper clad board with a constant current source and introduce eight precise resistors. When the touch pen touches any)

雷达点迹预处理技术，非常有用，硕士论文，介绍了点迹凝聚，野值剔除等(Radar trace points pretreatment technology is very useful, master' s thesis, introduces trace points cohesion, excluding outliers, etc.)
