再做出三位奇偶校验器并接入前面循环的输出，接到发光二极管上，要求在4和2时亮，6, 5, 3时灭 最后将时钟脉冲接入示波器CH1，奇偶校验器结果接入示波器CH2，并将时钟换成1024HZ<br>验收要求是<br>(1) 1HZ时观察6，5，4，3，2循环是否正确，奇偶校验器是否正常工作<br>(2) 1024HZ时，示波器上半部分显示CH1波形，下班部分显示CH2波形，要求显示两个周期左右，保证波形稳定做法：对减法计数器取反可得加法计数器，用161反馈置数法做出1——5循环再取反，奇偶校验器不用直接列异或表达式，可以只考虑出现的情况画卡诺图列真值表</p></li><li class="lvl-3"><p>时序电路设计，要求给定输入X与时钟信号CP，输出为Q0Q1Q2，X=0时输出4→5→6→4……的序列，X=1时输出0→1→2→0……的序列（1）X接逻辑开关，CP接1Hz脉冲，用数码管显示结果。（2）CP接1024Hz脉冲，用示波器显示稳定的图像，要求CH1接Q1，CH2接Q0。做法：用161做出3进制计数器，再将X取反接到数码管。这个思路很妙，不知道是怎么想到的。</p></li><li class="lvl-3"><p>电路实现010-011-100-101-110（搭完此电路，可以先用LED灯给老师验收） 以上述作为输出，进一步搭建奇偶判断电路或者能否被3整除的电路，用示波器观测输入与输出波形做法：常规的反馈计数法的加法计数器</p></li><li class="lvl-3"><p>利用JK触发器和与非门芯片，实现信号发生器，其能重复输出10011101信号，并完成连线做法：先搭000-111的八进制计数器，再画卡诺图列出输出信号的逻辑表达式进行译码。</p></li></ol><h3 id="VHDL语言">VHDL语言</h3><h4 id="基本结构">基本结构</h4><p><img src="image-20.png"

<code>_config.yml</code> 复制到 <code>Hexo</code> 根目录里（我这里路径为【C:/Hexo-Blog/blog-demo】），同时重新命名为 <code>_config.butterfly.yml</code>。以后只需要在 <code>_config.butterfly.yml</code>进行配置即可生效。Hexo会自动合併主题中的<code>_config.yml</code>和 <code>_config.butterfly.yml</code>里的配置，如果存在同名配置，会使用<code>_config.butterfly.yml</code>的配置，其优先度较高。</em></p><h3

class="lvl-2"><p><strong>隐晦规则</strong>：由于我们的make有自动推导的功能，所以隐晦的规则可以让我们比较粗糙地简略地书写Makefile，这是由make所支持的。</p></li><li class="lvl-2"><p><strong>文件指示</strong>：其包括了三个部分: 一个是在一个Makefile中引用另一个Makefile, 就像C语言中的include一样; 另一个是指根据某些情况指定Makefile中的有效部分, 就像C语言中的预编译#if一样; 还有就是定义一个多行的命令.</p></li><li class="lvl-2"><p><strong>注释</strong>：与python相同，#后面的均是注释内容</p></li><li
