本文叙述了一种适用于低速数字信道的地址编码时分交换系统的新的电路方案。文中对这种时分交换电路的原理作了简要的介绍后比较详细地描述了这种时分交换电路的逻辑结构,分析了这种交换电路对信号附加的偏畸变值。最后,本文提出了一种电位控制的矩阵式,N 中取1的互斥逻辑电路和电位控制的自动取样电路。
This paper describes a new circuit scheme for address coding time division switching systems suitable for low speed digital channels. In this paper, the principle of this kind of time-sharing exchange circuit is briefly introduced. After that, the logical structure of this kind of time-sharing exchange circuit is described in detail, and the additional distortion of this type of exchange circuit is analyzed. Finally, this paper presents a matrix of potential control, N in 1 mutually exclusive logic circuit and the potential-controlled automatic sampling circuit.
