摘　　要：从原理着手分析了影响航空视频电路电磁干扰的几个重要因素，采取降低时钟信号的干扰、保护敏感信号、数模混合电路统一接地、防止电源干扰、减少高频辐射对电路的影响等措施，提高视频电路板的电磁兼容设计，有效地提高电子产品的抗干扰能力和电子兼容性。Some important factors were analyzed which influenced the electromagnetic interference of the aerial video circuit and the measures were taken to improve the EMC design of digital-analog mix circuit board, such as reducing the interruption of clock signal, protecting sensitive signal, uniting mixed-signal circuits to earth, preventing the power interference, decreasing the electric influence of high frequency radiation and so on. It could improve the anti-interference ability and electromagnetic compatibility of electric products effectively.
