Abstract :
This paper presents the measurement and characterization of current supraharmonic emission levels caused by commonly used electronic devices. A system setup was developed and signal processing techniques were proposed to identify lower and higher frequency phenomena, emission frequency bands and distortion indicators. Finally, a summary of emission levels is presented.
