代入法的启发示搜索 我的代码实现是:按照自然语言各字母出现频率的大小从高到低(已经有人作国统计分析了)先生成一张字母出现频率统计表(A)--------(e),(t,a,o,i,n,s,h,r),(d,l),(c,u,m,w,f,g,y,p,b),(v,k,j,x,q,z) ,再对密文字母计算频率,并按频率从高到低生成一张输入密文字母的统计表(B),通过两张表的对应关系,不断用A中的字母去替换B中的字母,搜索不成功时就回退,在这里回朔是一个关键。

a Java program that reads in the following values from the standard input device (i.e. Keyboard) and writes its result on the standard output device (i.e. Console/Monitor): Inputs: A: the loan amount in dollars and cents (e.g. 150000.00). r: the net annual interest rate, expressed as an integer (e.g. 10 which means 10%) Y: the number of whole remaining years (for repayment) M: the number of remaining months Output: The program should calculate and output the amount of monthly repayments in dollars and cents as single value (e.g. $840.55)

im2dat.m is used to convert images to data which can be plotted using the standard MATLAB functions. This is very handy if you have plots on hardcopy and you want to convert them into data that MATLAB can use. The scanned image can be analysed by this function and the output will allow you to perform any calculation/manipulations that MATLAB can perform, e.g. curve fitting.

This a GUI that manages DSP analysis functions for wav-files (e.g., speech signals). Two functions (plotps.m and spect.m) are included for starters. You may write your own functions and integrate that into the GUI without much hassle (see instructions in the accompanying readme.txt file). Additional features like the snipper lets you trim the time series and save it as a separate wav-file. The GUI is a great tool for instructors in a DSP course and DSP researchers alike!

The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented. The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940). The design is fully pipelined for maximum throughput.
