fingerprint testing using matlab code

简单介绍雨滴的形成，运用流体力学相关知识，分析了雨滴下落所受的黏性阻力和压差阻力，考虑雨滴在空气中下落半径增加对雨滴速度的影响，得出了雨滴下落速度和雨滴半径的关系，对雨滴下落的收尾速度进行了一般的讨论。(Brief rain formation, the use of the knowledge of fluid mechanics, analysis of viscous drag and pressure drag the raindrops whereabouts suffered consider raindrops in the air, the whereabouts of the impact of increasing the radius of raindrops speed, to draw raindrops falling speed and raindrops radius the general analysis of the relationship between the terminal velocity of raindrops whereabouts.)

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

说明：  数字信号处理在电话语音拨号系统中的应用（自动拨号）(Digital signal processing in a telephone voice dialing system (automatic dialing))

模式识别方面的专业书籍，提供maylab仿真，，不过是英文版，对做毕设的同学有用(Pattern recognition of professional books, provide maylab simulation, but in English, the students complete set of useful to do)

求解随机动态规划的MATLAB程序，有需要的请下载(Solving stochastic dynamic programming)

验证可用，分析了该信号的时域、频域、倒谱，循环谱等,构成不同频率的调制信号。( Verification is available, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Constituting the modulated signals of different frequencies.)

说明：  测试实现时域LMS功能，需修改原始信号为模拟信号。(In order to realize LMS function in time domain, the original signal should be modified to analog signal.)
