Aliasing

Given a power spectrum (a plot of power vs. frequency), aliasing is a false translation of power falling in some frequencyrange outside the range. Aliasing can be caused by discrete sampling below the Nyquist Frequency. Thesidelobes of any Instrument Function (including the simple Sinc Squared functionobtained simply from Finite sampling) are also a form of aliasing. Although sidelobe contribution at large offsetscan be minimized with the use of an Apodization Function, the tradeoff is a widening of the response (i.e., alowering of the resolution).
