说明：  移动电话主要采用频率复用，但分配给移动电话的频段很少，远不能满足用户的需要。 因此就提出将地区划分成小区，称为蜂窝（Cell），每个蜂窝内使用一组频率，相隔一段距离后，相同的频率又可重复使用。 (The main use of mobile phone frequency reuse, but allocated to the small-band mobile phone, far from being able to meet the needs of users. Therefore proposed to be divided into residential areas, known as cellular (Cell), each use a set of cellular frequencies, separated by some distance, the same frequency can be reused.)

说明：  脉宽调制，亲自调试通过，是一个很好学习的资料(Pulse width modulation, self-testing, is a very good learning material.)

接到单片机上后，输出到示波器可以看到一定频率的方波，通过按键可以调节波形的频率，同时在显示屏上也可以产生对应的周期和频率，外加信号发生器，可以得出对应的周期频率(After being connected to the single chip computer, the square wave of a certain frequency can be seen when it is output to the oscilloscope. The frequency of the waveform can be adjusted by keystrokes. At the same time, the corresponding period and frequency can be generated on the display screen, and the corresponding periodic frequency can be obtained by adding a signal generator.)

合并果子，压缩是一种有效的减小数据量的方法，目前已经被广泛应用于各种类型的信息系统之中。 一种压缩文本文件的方法如下： 1. 原始文本文件中的非字母的字符，直接拷贝到压缩文件中； 2. 原始文件中的词（全部由字母组成），如果是第一次出现，则将该词加入到一个词的列表中，并拷贝到压缩文件中；否则该词不拷贝到压缩文件中，而是将该词在词的列表中的位置拷贝到压缩文件中。 3. 词的列表的起始位置为 1 。 词的定义为文本中由大小写字母组成的最大序列。大写字母和小写字母认为是不同的字母，即 abc 和 Abc 是不同的词。词的例子如下： * x-ray 包括两个词 x 和 ray * mary s 包括两个词 mary 和 s * a c-Dec 包括三个词 a 和 c 和 Dec 编写一个程序，输入为一组字符串，输出为压缩后的文本。(Fruit combined compression is an effective method for reducing the amount of data, has been widely applied to various types of information into the system. A method of compressing a text file is as follows: 1 original text file non-alphabetic characters, copy directly to the compressed file 2 words in the original document (all composed of letters), if it is the first time, then. The word is added to a word list, and copied to the compressed file otherwise the term is not copied to the compressed file, but the position of the word in the list of words copied to the archive. 3 the starting position is a list of words. The maximum term is defined by a sequence of text consisting of uppercase and lowercase letters. Uppercase and lowercase letters are considered different letters, ie abc and Abc are different words. Examples of the word as follows:* x-ray consists of two words x and ray* mary' s, including two words mary and s* a c-Dec consists of three words a and c and Dec to write )
