Prediction and Analysis of EMI Spectrum Based on the Operating Principle of EMC Spectrum Analyzers

EMC spectrum analyzers are popularly used for electromagnetic interference (EMI) measurement in power electronics systems. Depending on the specifications of EMI standards, the EMI measurement could be very time consuming. Conventionally, the fast Fourier transform is used to derive the EMI spectrum...
