Description: 数字带通滤波器的设计过程。共3个源程序。其中,dos.cpp为带通FIR的源程序,其中的滤波器阶数n,滤波器的低频fln,滤波器的高频fhn,窗函数w,可以按照自己的要求改变。这里采用的是汉宁窗。主函数main.cpp实现输入与fir的h(n)的卷积,输出结果Y(n),并将其存储在y.txt中。最后,graphics.cpp从y.txt读取数据,再由语句画出波形,可以清楚地看出计算结果是否正确,并进行比较。-digital band-pass filter design process. A total of three sources. Among them, dos.cpp FIR bandpass to the source, the filter order n, the low-frequency filter FLN, the high-frequency filter fhn, window function w, in accordance with the requirements change. Here is the Hanning window. The main function main.cpp achieve the input and fir h (n) convolution, the output Y (n), and store them in y.txt China. Finally, graphics.cpp y.txt read data from and then draw waveform statement, we can clearly see whether calculations are correct, and comparisons.

Description: 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

Description: 比较五种窗函数特性matlab程序:得到矩形窗、海明窗、三角窗、汉宁窗和布莱克曼窗图形。从仿真结果可知:矩形窗设计的过渡带最窄,但阻带最小衰减也最差。布莱克曼窗设计的阻带最小衰减最好,但过渡带最宽。-Comparison of characteristics of five kinds of window function matlab program: to be a rectangular window, Hamming window, triangular window, Hanning window and Blackman window graphics. From the simulation results we can see: the rectangular window designed for narrow transition zone, but the minimum stop-band attenuation is also the worst. Blackman window design of the stop-band minimum attenuation is best, but the transitional zone widest.

Description: 减少频谱泄漏,通常在采样后对信号加窗。在电机故障诊断领域,需同时考虑频率分辨率和频谱泄漏。应用最广泛的窗函数是汉宁窗。(To reduce the spectrum leakage, a window is usually added to the signal after sampling. In the field of motor fault diagnosis, frequency resolution and spectrum leakage should be considered at the same time. The window function is the most widely used Hanning window.)
