Descr iption: 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. Thu

Design frequency domain Ideal, Butterworth and Gaussian band pass filters to filter the input image. Use your own grayscale picture as the input image. The filters must be passing frequencies between radius of 30 and 120 frequency components of the

Sallen-Key filter was used in shaping of nuclear pulses and, with few stages of filters it was possible to reach the Gaussian waveform output. The characteristics of the shaped circuit base in Sallen-Key low pass filter were simulated and the opt

利用MATLAB设计各种滤波器，低通，高通以及带通滤波器，高斯白噪声的生成-Using MATLAB design of various filters, low pass, high pass and band-pass filter, Gaussian white noise generation
