EMI noise diagnosis and suppression for single-chip micyoco based electronic system

A systemic approach to diagnose and suppress electromagnetic interference (EMI) noise is proposed for single-chip micyoco (SCM) based electronic system. According to analysis the mechanism of SCM production conducted EMI noise and extract the common mode (CM) noise and differential mode (DM) noise, the EMI noise can be diagnosed and suppressed effectively. The feasibility of this method is testified by the experimental results.
