本次笔试考察的还是有点难度的,对于基础知识考察换了一种形式,总之,万变不离其中,基础知识掌握之后还是不怕的。
试卷一共有6道大题,没有选择题,难度瞬间上升,哈哈哈哈!!!
下边是具体的题目,仅仅是回忆,哈哈哈!!!
1. 题目
第一题
给了一段代码,最后问你结果是啥?
大概是这样:
char a, b;
unsignd char c, d;
第一个是给了个a是1,c是-1,算一下b=a+c 和 d = b
第二个是给了个a=-1, c=-1, a,c各右移一位,最后还是算这个b=a+c 和 d = b
第二题
简答:关于建立时间和保持时间的,要求画图,分析
第三题
简答:关于亚稳态的,什么是亚稳态?有什么危害?怎么消除?
第四题
计算:采样定理的考察。
给了采样频率100khz,先给了输入1khz,问你在哪采到信号的? 又给了输入60khz,问你在哪采到的信号?
我觉得答案应该是:1khz 和 40khz
解析:采样定理===> 采样频率大于等于最高频率的二倍,所以输入为1khz满足,则其在1khz可以采到完整的信号;而输入60khz,不满足采样定理,所以计算方式为:绝对值(n * 100khz - 60khz )= 40khz,意思是找最近的即可。
第五题
编程:跨时钟域的处理,一个单比特,一个多比特,注意一下就行!
第六题
编程:用C语言给数组排序。
