随着电路系统复杂性的提升,模拟电路故障率占据总故障率的大部分,所以,加强模拟电路故障诊断与排除的研究十分重要。从分析模拟电路的故障类型及原因出发,探讨在模拟电路故障诊断过程中所采用的几种常见诊断方法,以及未来的发展趋势。 With the improvement of the complexity of the circuit system, the failure rate of the analog circuit occupies most of the total failure rate. Therefore, it is very important to strengthen the research on fault diagnosis and elimination of analog circuits. Starting from the analysis of the types and causes of the analog circuits, several common diagnostic methods used in the analog circuit fault diagnosis are discussed, and the future trends are also discussed.
