在无线电设备中,集成电路的应用愈来愈广泛,对集成电路应用电路的识图是电路分析和设备维修中的一个重点,也是难点之一。笔者在从事《电子技术》教学和指导学生进行电子实习过程中,发现许多学生对集成电路应用电路的识图比较困难,从而影响对电路原理的分析及故障的判断和排除。下面谈谈集成电路应用电路的识图方法。一、集成电路应用电路图的功能要对电子电路的原理作出正确分析,首先必须了解集 In the radio equipment, the application of integrated circuits is more and more widely. It is one of the key and difficult problems in the circuit analysis and equipment maintenance to recognize the circuit of the integrated circuit. The author engaged in “electronic technology” teaching and guiding students in the process of electronic internship, found that many students of IC application circuit identification is more difficult, thus affecting the analysis of circuit theory and fault diagnosis and troubleshooting. Here to talk about the IC application circuit of the map method. First, the function of integrated circuit application circuit diagram To make the correct analysis of the principle of electronic circuits, we must first understand the set
