Good morning Mike,
Strongly agree. But as KB4T observes, they can also suffer from
poor design. Another example. Many of us have converted our
Ethernet installations to use 802.11b (WiFi). These systems can work
fine and I've never seen interference TO their operation, but the
WiFi hardware is often radiates from its poorly shielded enclosure
and often puts out common mode that is radiated by the cable between
it and a cable or DSL router.
