Glossary definition of 'Aliasing components'
Aliasing can take place when a frequency above the folding frequency of an EUT is applied to its analogue input (or where internal down-sampling occurs). Aliasing is manifest by the appearance of a spurious frequency component at the EUT's output, below the folding frequency by the same frequency as the input stimulus is above the folding frequency. Thus the stimulus has been 'folded' about the folding frequency.see also:
