设信号 ，用 对x(t)采样得x(n)，是否会发生频谱混叠？现利用FFT分析其频谱。 1．编程绘制该信号的波形。 2．若令N=16，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 3．令N=1024，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 4．分析2、3的运算结果。 设计调试报告要求： 1．工作原理简述； 2．设计思路； 3．难点及解决方法； 4．设计、调试结果及分析； 5．程序文本及操作步骤。(based signal used to x (t) in the sample x (n), whether there will be a spectrum aliasing? FFT analysis is the use of their spectrum. 1. Programming mapping of the signal waveform. 2. If so N = 16, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 3. Order N = 1024, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 4. Analysis of two, three computational results. Design debugging reporting requirements : 1. Principle outlined; 2. Design; 3. Difficulties and solutions; 4. Design, debugging and analysis of results; 5. Text and operating procedures steps.)

BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets. An advantage of Birch is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering for a given set of resources (memory and time constraints). In most cases, Birch only requires a single scan of the database. In addition, Birch is recognized[1] as the, "first clustering algorithm proposed in the database area to handle noise (data points that are not part of the underlying pattern) effectively".
