Abstract:

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.
