PRECAUTIONS
When input signal contains the element of one half or less
of the sampling frequency (at 10 m sec/div, 10 kHz by
0.1 m s e c , or 1 / 1 0 0 of 10
m
s e c ) , even though this is in
the critical range in use, a phenomena (Aliasing) will occur
by which as if some element other than input signal, which
in fact does not e x i s t , is indicated in the frequency range of
one half or less of the sampling frequency.
