本文是以T型网络为例较全面的介绍了发射机自动调谐系统逻辑电路的设计方法。全文主要包括两大部分。第一部分是系统调谐程序的编制,介绍了T型网络的调谐原理,从而得到网络的实际调谐图和自动调谐系统的调谐程序流程图。它为系统逻辑电路的设计提出了要求,第二部分主要是介绍系统逻辑电路的设计。在设计系统逻辑电路时必须分段进行,首先按照功能,把整个逻辑划分为若干分逻辑,然后再根据各分逻辑的技术要求,运用数字逻辑电路的设计方法,对各分逻辑电路进行设计。
This article is a T-type network as an example of a more comprehensive introduction to the transmitter automatic tuning system logic circuit design. The full text includes two major parts. The first part is the compilation of the system tuning procedure, introduces the tuning principle of the T network, and obtains the actual tuning diagram of the network and the flowchart of the tuning procedure of the automatic tuning system. It puts forward the requirements for the design of system logic circuit. The second part mainly introduces the design of system logic circuit. In the design of system logic must be carried out in stages, first of all in accordance with the function, the entire logic is divided into a number of sub-logic, and then according to the technical requirements of the sub-logic, the use of digital logic circuit design method, the sub-logic circuit design.
