引言在通讯中,数字技术的应用在许多方面不断地增加,一例是高频无线电、卫星通讯、对流层散射通讯系统中的手控自动化,另一例是精确准备的信息和数据进入交换系统。此外,现在的卫星通讯系统中,例如 MARISAT、MAROTS 和时分多路存取也采用数字定向。为这些目的所设计的设备包括大量的数字数据处理,因此在这方面应该考虑微处理机的应用。在采用微型组件系统中,如何选择微处理机的基本设计来自于对问题的充分分析,除了对价格、时间、体积、环境等这些条件很好考虑以外,还要估计到许多新的因素。已市售的
INTRODUCTION The use of digital technologies in communications has constantly increased in many respects. One is the manual automation of high-frequency radios, satellite communications, and tropospheric scatter systems, and the other is the placement of precisely prepared information and data into the exchange system. In addition, the current satellite communications systems, such as MARISAT, MAROTS and time division multiple access also use digital orientation. The equipment designed for these purposes includes a large amount of digital data processing, so microprocessors should be considered in this regard. The basic design of how microprocessors are used in a microassembly system comes from a thorough analysis of the problem, with many new factors to be estimated in addition to good consideration of terms such as price, time, volume, environment and so on.
