麻省理工学院introduction to matlab课程作业指导，包含matlab实例（3），相互交流(same as before excellent matlab exercises homework for improving matlab )

最近用Mega128写了一个128点FFT程序，浮点运算，加汉宁窗。由于窗函数和旋转因子通过查表得到，所以速度还可以，程序中给的初值是通过高速AD采集的20KHz正弦信号。计算结果与Matlab的FFT函数得到的结果相同。 (Mega128 recently wrote a 128-point FFT procedures, floating-point operations, Hanning window. Since the window function and the twiddle factor look-up table has been adopted, so the speed can also be, the initial value to the process through high-speed AD collected 20KHz sinusoidal signal. The calculation results with the Matlab)

Subject: Statistical Signal Processing. Scope: Radiophysics. We consider the statistical criterion of Student (t-test), a truncated-prednazna to test the hypothesis of equality of average values of two samples of ma-logo, each of which has a normal distribution law with identical Scientifical variance.
