设计一个哈夫曼编码器 要求对一段数据序列进行哈夫曼编码，使得平均码长最短，输出各元素编码和编码后的数据序列。 ① 组成序列的元素是[0-9]这10个数字，每个数字其对应的4位二进制数表示。比如5对应0101，9对应1001。 ② 输入数据序列的长度为256。 ③ 先输出每个元素的编码，然后输出数据序列对应的哈夫曼编码序列。(Designing a Huffman Encoder Huffman coding is required for a data sequence to minimize the average code length and output the coded and coded data sequence of each element. (1) The elements that make up the sequence are the 10 digits [0-9], and each digit is represented by its corresponding 4-bit binary number. For example, 5 corresponds to 0101, 9 corresponds to 1001. (2) The length of the input data sequence is 256. (3) First output the encoding of each element, and then output the Huffman encoding sequence corresponding to the data sequence.)

可用于测量ADC的信噪比SNR，信纳比SINAD，无杂散动态范围SFDR，总谐波失真THD，得到频谱图及时域图的MATLAB作图,ADC测试方法是fft法(The following program code plots the FFT spectrum of a desired test tone. Test tone based on coherent sampling criteria, and computes SNR, SINAD, THD and SFDR.)

通过本书，读者不仅能掌握使用R及相关算法包来快速解决实际问题的方法，而且能从实际问题分析入手，到利用R进行求解，以及对挖掘结果进行分析的全面训练(Through this book, readers can not only master the method of using R and relevant algorithm packages to quickly solve practical problems, but also start from the analysis of practical problems to the comprehensive training of using R to solve problems and analyzing mining results)
