When driving a cable it is important to terminate the cable
to avoid unwanted reflections. This can be done in one of
two ways: single termination or double termination. With
single termination, the cable must be terminated at the
receiving end (75 to ground) to absorb unwanted en-
ergy. The best performance can be obtained by double
termination (75 in series with the output of the amplifier,
and 75 to ground at the other end of the cable). This
