As
a
good high-frequency response
is
needed
to
reproduce nearly
vertical edges, perhaps
one
could guess that
an
extended
low-
frequency response
is
required
to
reproduce horizontal parts
of
waveforms.
In
fact,
if a
pulse switches between
two
truly horizontal
levels,
then
the
frequency response must extend down
to
zero
frequency.
In
other words
