The lateral inhibitory network was studied as a spatial digital filter. When the distribution function of the inhibitory coefficient is Gaussian, the network isnotonly a filter which suppresses the lower spatial frequency components and thus enhancing the contrast, or a higher frequency pass filter, but it is also an inverse Gaussian filter which can recover the image blurred by the random disturbance in the medium, thus enhancing contrast and raising the 'signal-noise ratio'.The difference...

When the distribution function of the lateral inhibition coefficient is Gaussian, the nonrecurrent inhibition network can not be an inverse Gaussion filter. In general, to possess the same given transfer function, fewer lateral branch interconnections and a simpler distribution of the lateral inhibition coefficient are needed for a recurrent network than for a nonrecurrent one, so that the recurrent inhibitory network can be constructed or regulated more easily.

本文从空间数字滤波器的角度研究了侧抑制网络的功能。当侧抑制系数是高斯分布的情况下,侧抑制网络不仅仅是抑制空间低频分量而提高反差的滤波器,也不仅仅是空间高通滤波器,它还可能是一种逆高斯滤波器,具有使因随机媒质干扰而变模糊的图象恢复清晰的作用,从而提高了图象的反差,提高了“讯噪比”。另外,本文讨论了循环抑制网络和非循环抑制网络的区别。在侧抑制系数都是高斯分布的情况下,非循环抑制网络不能起到逆高斯滤波器的作用。就一般的情况而言,要达到某种相同的频率响应函数,循环网络较之非循环网络只需较少、较短的侧枝联结,侧抑制系数的分布也较简单,从而循环抑制网络便于结构和调节。

The time which is neccesary for synch-acquisition over a channel with a given signal noise ratio is discussed in detail. The dynamic response of the DPLL is obtained and the formula for calculating the time for holding synchronization is also derived in the paper.

A digital phase-locked loop is described in this paper. It is different from the convenient DPLL with its shorter time for synch-acquisition and longer time for holding synchronization. The time which is neccesary for synch-acquisition over a channel with a given signal noise ratio is discussed in detail. The dynamic response of the DPLL is obtained and the formula for calculating the time for holding synchronization is also derived in the paper. It is also emphasized that increasing the time for holding synchronization of the described DPLL is possible with some improvement on stability of crystal voltage control oscillator. Finally some experimental results are briefly given.
