FFT_TEST

THIS matlab code is STTD

用Matlab编程编程是实现的扫雷游戏，不足之处请指教(Programming with Matlab programming is to achieve the minesweeper game, shortcomings Please advise)

这是一个基于matlab图像复原处理包，其中包括图像的模糊、维纳滤波、盲反卷积、点扩散函数和光学转换函数互相转化(This is a matlab-based image restoration processing package, including the images fuzzy, Wiener filtering, blind deconvolution, point spread function and optical transfer function to transform)

该程序是使用matlab语言编写的时钟，与北京时间完全相同(It is a clock compiled by matlab language.)

说明：  超声波数值模拟，通过matlab模拟声场的传播(ultrasonic simulation)

说明：  script for the robot control

Converts binary data of any format in a string to floating point decimals of a defined fraction size. the intsize input parameter defines the size of the exponent and sets the fixed point location in the binary number. se accompanied matlab program for test of this function

录制自己的一段语音，时间控制在15秒到30秒左右；利用wavread函数对自己的语音进行采样，记住采样频率。 （1）画出原始语音信号的时域波形，而后以1秒为间隔，求出每秒数据的功率谱。 （2）根据语音信号特点，分别设计FIR及IIR滤波器，分别画出滤波器幅频和相频特性曲线。用设计的滤波器对信号滤波，画出滤波后时域波形。用sound函数回放语音信号。 （3）求出特征频段语音信号随时间变化的曲线（每间隔0.05秒求一次功率谱）。 (Record your own voice for some time (15 seconds to 30 seconds) use wavread function of the voice samples, remember the sampling frequency. (1) Draw the original speech signal in time domain waveform, and then to 1 second intervals, the data obtained power spectrum per second. (2) According to the voice signal characteristics, FIR and IIR filters were designed, namely to draw the amplitude and phase frequency characteristic curve. With the design of the filters on the signal filtering, to draw the filtered time-domain waveform. Playback with sound function of the speech signal. (3) Find the characteristic band speech signal curve over time (0.05 seconds intervals seeking a power spectrum.))

该程序产生MSK和GMSK复基带信号，并在同一图中作出二者的功率谱，对处理实际信号时非常有帮助(The complex base signals of MSK and GMSK are produced, respectively. The power spectral density of the two signals are darwn in the same figure, which really helps for pratical signal processing)
