| Abstract: | Antiinterference technology, consisting of hardware and software antiinterference, involves many subjects. Confronted the universal EMI in practical projects, this paper summarizes the hardware reliability and antiinterference design, analyzes EMI resources, approaches and aftereffects, puts forward the hardware reliability and anti-interference design thought in embeded system. Based on this thought, the design of power supply, signal transmitting channels, special electromagnetic field and elements optimization in circuit has been summarized detailedly,and also the power, clock, signal delay matching and holistic layout in PCB design. |
