In the early 1960s research into radar signal synthesis produced important formulas describing the action of the two-dimensional Fourier transform on auto- and crossambiguity surfaces.
      
It is shown that the one-dimensional sampling sets correspond to Bessel sequences of complex exponentials that are not Riesz bases for $L^2[-R,R].$ A signal processing application in which such sampling sets arise naturally is described in detail.
      
Given a bandlimited signal, we consider the sampling of the signal and some of its derivatives in a periodic manner.
      
We present a method for finding the dual frame and, thereby, a method for reconstructing the signal from its samples.
      
We show that if no sampling of the signal itself is involved, the sampling is not stable and cannot be stabilized by oversampling.

The effects of parameters of optical beam splitter on-Doppler signals in a dual beam LDV were discussed, and the formulae about these effects were given. The effect on signals caused by the influence of different ratios of fringe separationto diameter separations to diameters of scattering particles was calculated by the author. It showed(?)a great difference between the round cross section of particles and the square cross section that calculated by others before.With an example of designing a laser...

The effects of parameters of optical beam splitter on-Doppler signals in a dual beam LDV were discussed, and the formulae about these effects were given. The effect on signals caused by the influence of different ratios of fringe separationto diameter separations to diameters of scattering particles was calculated by the author. It showed(?)a great difference between the round cross section of particles and the square cross section that calculated by others before.With an example of designing a laser sea current meter, the method electing the spacial period of fringe with respect to match the diameter of scattering particles was recomended. Finally, an configuration in which those parameters could be adjected independently was introduced.

本文着重讨论了双光束条纹型激光多普勒测流系统中,光学分束系统参数与散射信号的关系,列出了有关的公式。计算了园形截面的散射颗粒直径与干涉条纹周期呈不同比值时对信号的影响,其结果与以前采用矩型截面进行计算的结果差异较大。以设计一台激光海流计为例,推荐一种以选择与散射粒径相匹配的条纹周期为出发点的光学参数选择方法。最后介绍作者提出的为实现这种选择的光学布置。

A wavelength method for speech recognition is described in this paper. In this method, the sequences of wavelength are extracted from the preprocessed zero-crossing waves of sound signals and the features of their distribution are analyzed. Experiments have been performed on Computer 109 and Computer 111, the correct recognition rate of 10 spoken Chinese digits is about 98.7% for a specific speaker. The principle of recognition and the processing method are also presented.

本文介绍一种“波长法”,即从预处理的声音零交叉波中提取波长序列,分析其分布特征,用于语音识别。此法曾在我国国产109和111电子计算机上进行试验,对10个口呼汉语数字的单人识别率可达98.7%左右。本文介绍了有关原理和处理方法。

The Binodal signal flow graphs are presented and the topological formula of deter-minant is derived which overcomes the drawback of term-concelling in the case of Mason formula.Finally application examples of this formula is given.

本文讨论两种节点的信号流图,并推导图行列式的拓扑公式。该式克服了直接应用Mason公式时带来相消项的缺点。最后,通过实例说明公式的应用。
