2.接收机所讨论的接收机的问题分为三大部分:第一,方框图;第二,增大作用距离;第三,线路改进。方框图的探讨包括在方框图一节中,增加作用距离的问题是射频关一节的一部分,电路改进问题贯串于整个接收机这一章中。对接收机的评价在本报告的第七章中讲述,优选试验结果在各单元中讲述。
2. Receiver The receiver discussed is divided into three major problems: first, the block diagram; second, to increase the range of action; third, the line is improved. The discussion of the block diagram is included in the block diagram section. The issue of increasing the range is part of the section on radio frequency offsets. The problem of circuit improvement runs through the entire receiver. The evaluation of the receiver is described in Chapter 7 of this report, and the preferred test results are described in each cell.
