程序

此源码不是很难，但是个人所写，主要是对数字信号处理的数字滤波的一种实现。-This source code is not difficult, but written by individuals, mainly on digital signal processing to achieve a digital filter.

一、 实验目的 1. 掌握典型序列的产生方法。 2. 掌握DFT的实现方法，利用DFT对信号进行频域分析。 3. 熟悉连续信号经采样前后频谱的变化，加深对时域采样定理的理解。 4. 分别利用卷积和DFT分析信号及系统的时域和频域特性，验证时域卷积定理。 二、实验环境 1． Windows2000操作系统 2． MATLAB6.0(First, the purpose of the experiment 1. master the method of producing typical sequence. 2. master the realization method of DFT and use DFT to analyze the signal in frequency domain. 3. familiar with the change of the frequency spectrum before and after the continuous signal sampling, deepen the understanding of the time domain sampling theorem. 4. the time domain and frequency domain characteristics of the convolution and DFT analysis signals and systems are used to verify the time domain convolution theorem. Two. Experimental environment 1. Windows2000 operating system 2. MATLAB6.0)

邮票问题:设一国家发行n种不同面值的邮票，并且每封信至多允许贴m张邮票，对于给定的m,n值，写一个算法求出从邮资1开始在增量为一的情况下可能获得的邮资值的最大连续区域以及获得这个区域的各种可能面值的集合。如，当 n=4,m=5,若有面值为（1，4，12，21）的四种邮票，则邮资最大的连续区域为1到71。还有其他面值的四种邮票可组成同样大小的区域吗-stamp issue : Let a national issue n different denominations of the stamps and letters each allow up to m stamp affixed, to the m, n, write an algorithm derived from a postage in an increment of the circumstances, may obtain a postage value of the maximum continuous access to this region and regional various denominations could assemble. For example, when n = 4, m = 5, if the values of (1,4,12,21) of the four stamps, postage largest regional consecutive 1-71. There are four other denominations of the stamps can be the same size as the composition of the region? ?
