文章探讨了未来战术军用通讯对频率和时间控制的要求。对军用或其他应用中的频率控制标准的要求亦作了评述。对这些标准的效果进行了研究,以及研究了美军中现计划加强全气候工作时,对频率综合器的要求。近来由于单边带采用了晶体滤波器,已能指出所要求的特性和通讯系统的目的,对全数字的传输和开关系统的比对问题的研究已牵涉到军用通讯系统的要求。 The paper explores the future requirements of tactical military communications for frequency and time control. The requirements for frequency control standards in military or other applications are also reviewed. Studied the effects of these standards, and studied the requirements for the frequency synthesizer in the U.S. military when it plans to step up its work on the whole climate. Recently, the use of crystal filters in single sidebands has led to the identification of required characteristics and the purpose of communication systems. Research into the alignment of all-digital transmission and switching systems has involved the requirements of military communication systems.
