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: Description: Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the frequency domain. Thus, taking the Inverse Fourier Transform of this transfer function we get a filter characteristics closely resembling to the Gabor filters. The Gabor filter is basically a Gaussian (with variances sx and sy along x and y-axes respectively) modulated by a complex sinusoid (with centre frequencies U and V along x and y-axes respectively).
