The Evolution of EMI Receivers
Since the discovery of electromagnetic interference (EMI) in the early 1900s, the need for testing for radiated emissions continues to grow as products get more complicated. The
time to test has also grown, and, in some cases, can take days to complete. The introduction of
fast Fourier transform (FFT) technology into EMI receivers can greatly decrease the required testing time, but is it applicable for everyone?
