Lisa is analyzing the questionnaire about online shopping.
Lily: Hi, Lisa. Pretty busy？ Right？
Lisa: Yeah, I'm collecting data from the questionnaires for the online shoppers on the ().
Lily: Really？ Sounds interesting.
Lisa: Well, the results are quite(). What do you think are the most popular things people buy online？
Lily: Definitely, clothes.
Lisa: No, at first I thought so too, but the results show that I'm wrong.
Lily: How could that be？ If the most popular thing being sold online is not clothes, then what is it？
Lisa: Don't feel surprised.()the survey, online courses()the first place, especially the courses for accounting and languages.
Lily: Really？ It's unbelievable. What's next？ It should be the clothes or snacks, right？
Lisa: You are wrong again, the results shocked me too. Following online courses, health products()the second place.
Lily: That really surprised me, too. You just taught me a lesson and()my understanding about online shopping.
Lisa: Have a seat, and let me show you some more unexpected results.
Lily: OK! I'm really()about it.
若用二次探査法解决冲突，求“下一个空位”的探查序列为：
其中，H0是第一次求得的散列地址，Hi是第i次求得的散列地址，m是散列表的大小。
(1)相邻的地址Hi与Hi-1之间是什么关系？
(2)为保证散列地址序列的地址不会循而往复地重迭，m应设为什么数？装填因子α应如何取值？
(3)为保证在删除时不中断搜索链，可对被删记录做逻辑删除。为此，每个散列地址有3个状态，除了Active(正在使用)和Deleted(删除)状态外，还应有一个什么状态？

一个二阶IIR滤波器的系统函数为
现用b位字长的定点制运算实现它,尾数作舍入处理。
(1)试计算直接I型及直接II型结构的输出舍入噪声方差
(2)如果用一阶网络的级联结构来实现H(z).则共有六种网络流图.试画出有运算舍入噪声时的每种网络流图并计算每种流图的输出舍入噪声方差。
(3)用并联结构实现H(z),计算输出舍入噪声方差。几种结构相比较.运算精度哪种最高,哪种最低？
(4)考虑动态范围,因为系统中任一节点的输出值(包括整个系统的输出节点)等于从输入到此节点的单位冲激响应与系统输入的卷积和,可以表示成
其中yi(n)为第i个节点的输出,hi(n)为从输入到第i个节点的单位抽样响应。对于输出节点来说yi(n)=y(n),hi(n)=h(n)。由上式可得
也就是说，一个网络的最大输出电平不一定在输出端.可能在某一中间节点,利用这一关系以及xmax,试求以上各种网络中每一个的最大ymax.要求网络的所有节点上都不发生溢出,即要最大输出ymax＜1.这样即可求得最大的输入xmax(不发生溢出时)。试求以上各个网络的xmax
(5)设输入信号是白噪声序列.它的幅度在-xmax到xmax之间均匀分布.按照已求出的每一滤波器结构的最大输入xmax求每种结构在输出端的噪声信号比值(输出噪声方差与输出信号均方值之比)。问哪种结构输出噪声信号比值最低。
(d) Family owned and managed businesses often find delegation and succession difficult processes to get right.
