Altera SOPC嵌入式系统设计教程 第1章 概述 SOPC(System On Programmable Chip,可编程的片上系统)是Altera公司提出来的一种灵活.高效的SOC解决方案.它将处理器.存储器.I/O口.LVDS.CDR等系统设计需要的功能模块集成到一个可编程器件上,构成一个可编程的片上系统. 1.1 SOPC及其技术 现今,可将SOPC视为是基于FPGA解决方案的SOC.与ASIC的SOC解决方案相比,SOPC系统及其开发技术具有更多的特色,也有多种途径可构成SOPC方…

代码: h = [-4, 1, -1, -2, 5, 0, -5, 2, 1, -1, 4]; M = length(h); n = 0:M-1; [Hr, w, c, L] = Hr_Type3(h); c L cmax = max(c) + 1; cmin = min(c) - 1; figure('NumberTitle', 'off', 'Name', 'Exameple 7.6') set(gcf,'Color','white'); subplot(2,2,1); stem(n, h)…

注意:高通的线性相位FIR滤波器,不能是第2类,所以其长度必须为奇数.这里取M=31,过渡带里采样值抄书上的. 代码: %% ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ %% Output Info about this m-file fprintf('\n***********************************************************\n'…

又到清明时节,…… 注意:带阻滤波器不能用第2类线性相位滤波器实现,我们采用第1类,长度为基数,选M=61 代码: %% ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ %% Output Info about this m-file fprintf('\n***********************************************************\n');…

代码: 子函数ampl_res function [Hr,w,P,L] = ampl_res(h); % % function [Hr,w,P,L] = Ampl_res(h) % Computes Amplitude response Hr(w) and its polynomial P of order L, % given a linear-phase FIR filter impulse response h. % The type of filter is determined aut…
