hello all,

I have a little topic I couldn't understand completely (or as much I want to

As a rule of thumb it is well known to use a filter to cut all frequencies
above half the sample frequency. But I guess, there are cases that doesn't
need this

I have indeed omitted an anti-aliasing filter when I'm confident of the
bandwidth of the input signal.
