蜂鸣器在单片机上的应用,汇编语言,附原理图及说明学习文档 蜂鸣器的正极性的一端联接到5V电源上面，另一端联接到三极管的集电极，三极管的基级由单片机的P2.4管脚通过一个与非门来控制， 用户可以通过程序控制P2.4管脚的置低和置高来使蜂鸣器发出声音和关闭。 蜂鸣器的声音大小及音调可以通过调整P2.4管脚的置高时间及输出的波形进行控制，这一点可以在调试程序的时候来试验。-On the buzzer in single-chip applications, assembly language, with a schematic diagram and instructions to study documents the positive polarity of the end of the buzzer connected to the 5V power supply above, the other end connected to the transistor" s collector, the base level by the single-chip transistor Machine P2.4 pin through a NAND gate to control, the user can be programmed to set pin P2.4 low and set high to make the buzzer sound on and off. Buzzer sound size and pitch can be set by adjusting the P2.4 pin of the high time and output waveform control, and this point could be the time to test the debugger.

实验五 哈希表
[实验目的]
1、哈希函数的选择
2、用链表创建哈希表
3、输出哈希表
[题目]
假设人名为中国人姓名的汉语拼音形式。待填入哈希表的人名共有30个，取平均查找长度的上限为2。哈希函数用除留取余数法构造。用链表来处理冲突。-Five experimental hash table [the experiment was] one, the choice of hash function 2, create a hash table with linked list 3, the output hash table [subject] assumptions of people known as the Chinese name for the Chinese Phonetic Alphabet forms. Hash table to be populated with the names of a total of 30, taking the upper limit of the average search length of 2. Hash function used in addition to collecting more than the number of law structure. Used to deal with the conflict list.

定时同步是UWB通信系统中至关重要的问题，定时偏差和抖动将严重影响接收机性能。一般定时同步分为捕获和跟踪两个阶段。在捕获阶段，要求接收机快速搜索信号到达时间，并根据搜索结果调整接收机定时.-Timing Synchronization UWB communication systems is of vital importance to the issue, timing error and jitter will seriously affect the receiver performance. Timing Synchronization generally divided into two stages to capture and track. In the capture stage, the request receiver Quick Search signal arrival time, and adjust search results according to the receiver from time to time.
