In this paper the information transmitting rate of delta-modulation (△M) system is discussed and compared with PCM system. It points out that the principal way of increasing the information rate is to decorrelate the modulating signal. The formulae of computing the signal-to-noise ratio of single integration and double integration delta-modulation systems are given. The signal-to-noise ratios and thier relations to pulse repetition frequency for both systems are calculated with typical modulating signal and...

In this paper the information transmitting rate of delta-modulation (△M) system is discussed and compared with PCM system. It points out that the principal way of increasing the information rate is to decorrelate the modulating signal. The formulae of computing the signal-to-noise ratio of single integration and double integration delta-modulation systems are given. The signal-to-noise ratios and thier relations to pulse repetition frequency for both systems are calculated with typical modulating signal and the results are compared with PCM system. The views in the problem of compression-expansion with practical meaning for both PCM and △M systems are presented. The △M system is reviewed from the point of view of information theory.

A real time digital vocoder which has 2400 b/s data transmission rate, has been developed The speech quality of the vocoder is excellent,and it can be used in low bit rate speech communications. Based upon the acoustics of speech and information theory of chinese characters, we have designed a 2400 b/s digital channel vocoder by means of the simulation in a general-purpose computer and implemented this vocoder hardware by TTL small and medium scale integrated circuits. The listening tests have proved that synthetic speech intelligibility and naturalness are both satisfactory. Moreover, hardware is. simple. Thus it can be adapted for communication engineering.

This paper makes a survey of developments in the domain of information theory in the last thirty years.Five problems have been discussed,namely:Shannon Theory;channel coding;mo- dern information theories;the detection and estimation theory;and the information or signal processing. Since attention paid to the first and third problems by workers in our electronics circles is in general insufficient,an account of the major historical achievements in those problems have been concisely presented.In respect of the detection and estimation theory,the difference between the theory of quantum detection and estimation and the theory of classical signal detection and parameter estimation is simply stated.Besides these five problems,the author suggests three other areas deserving of fur- ther attention of our information workers in the near future,namely:cryptography;the relations between information theory and other branches of science;and the information science.

本文回顾了三十年来的信息论的发展。这个回顾分为五个问题,即 Shannon 信息论,信道编码,近代信息论,检测和估计理论,信息或信号处理问题。一般说来,国内的电子工作者对第一和第三两个问题注意不多,所以扼要地陈述了历史上较重要的成果。在检测和估计理论方面简单地阐明了量子检测和估计理论与经典的信号检测和参数估计理论的不同点。在这五个问题以后,作者又提出在近期我国信息论工作者应该给予注意的三个方面。它们是:保密学,信息论与其它学科的关系和信息科学。
