Anti-Alias Considerations for Spectral
Measurement Applications
Input frequencies greater than one half the output
word rate (CONV = 1) may be aliased by the con-
verter. To prevent this, input signals should be lim-
ited in frequency to no greater than one half the
output word rate of the converter (when CONV
=1). Frequencies close to the modulator sample rate
(XIN/2) and multiples thereof may also be aliased.
If the signal source includes spectral components
above one half the output word rate (when CONV
= 1) these components should be removed by
means of low-pass filtering prior to the A/D input
