Title:
A Novel Realtime Time-Domain EMI Measurement System Based on Field Programmable Gate Arrays 
Abstract:
In the past and now measurements are carried out by EMI-receivers operating in frequency-domain. By a time-domain EMI (TDEMI) measurement system the measurement time can be reduced by several orders of magnitude. In this paper a novel real-time TDEMI measurement system that uses a direct hardware implementation of the short time fast Fourier transform (STFFT) and the detector modes is described. The hardware implementation on field programmable gate arrays (FPGAs) allows to process the input sig...    »
