机载计算机高速数字电路系统的硬件抗干扰设计

摘要

This paper first analyzes the onboard computer cause of high-speed digital circuit system interference noise, and then analyzes the interference noise coupling way, finally expounds the hardware anti-interference design. Hardware anti-interference design content includes:several typical circuit components selection, power supply design, design, and bus design.%文章首先分析了机载计算机高速数字电路系统干扰噪声产生的原因，然后分析了干扰噪声耦合途径，最后重点阐述了硬件抗干扰设计，其中硬件抗干扰设计内容包括：元器件选择、电源地设计、几种典型电路设计、总线设计等。
