本文討論一种利用譯码网絡构成的反馈编码器——递次比较编码器。它是目前研究的时間划分多路语言编码系统的中心部份。利用它,可以将语言的取样信号变换为相应的二进位数字信号。本文叙述了递次比較編码器的构成原理,介绍了主要的电路形式,给出了初步实验结果,同时比較了几种典型的电子綫路编码方法。可以看出,递次比较编码器较之其它类型的编码器有简单,稳定,可靠和准确度高等优点。因此,是个后脈碼调制端机的研究中一个值得注意的方向。
This article discusses the use of a decoder network consisting of feedback encoder - successive comparison encoder. It is the central part of the time-partitioned multi-language coding system currently studied. Using it, the sampled signal of the language can be transformed into a corresponding binary digital signal. This paper describes the composition of the pass-by-pass encoder principle, introduces the main circuit forms, gives the preliminary experimental results, and compares several typical electronic circuit coding methods. It can be seen, compared to other types of encoders than other types of encoder has a simple, stable, reliable and high accuracy. Therefore, it is a noteworthy direction in the research of the pulse code modulation terminal.
