Glossary definition of 'Imaging components'

Imaging can take place in an EUT with a D/A converter or which performs digital up-sampling. It is manifest by the appearance at the EUT`s output of a spurious frequency component above the folding frequency by the same frequency as the stimulus is below it. It is caused by insufficient stop-band attenuation in the EUT, and is most noticeable close to the folding frequency.
