Q:
Using
the
tektronix
2445B
oscilloscope,
what
are
the
measured
frequency,
period
and
amplitude
of
each
signal?

Q:
How
does
this
compare
to
the
measurements
taken
with
the
RAPIDS
system?
A:
The
RAPIDS
system
is
not
as
accurate
as
the
Tektronix
oscilloscope.
The
summed
wave
is
much
easier
to
read
on
the
RAPIDS
system.
The
following
plots
are
attached
in
order:
