SCM and Alias Filters
In general, most SCM have built-in Low Pass (LP) filters as part of their design. In addition to the obvious benefits of such filtering, there is the very important subtle benefit. Namely, SCM with high quality multi-pole LP filters can be viewed inherently as having anti-alias filtering capabilities.
