Hi All,
Well, its that time of the month when I get an itch to write something.
So here goes....
Troubleshooting intermittent design problems can be a real time and
resource burner in the development lab. Sometimes intermittent problems
can be caused by lack of system immunity to noise on system cables. This
month's technical tidbit at www.dsmith.org covers a technique for
determining the magnitudes and relative directions of noise currents on
system cables. This information can often lead to a solution of the
problem. In addition, a design technique for minimizing system
sensitivity to noise currents on cables is discussed. A modem example is
used to show how the method is applied and scope data is used to
illustrate how the data is interpreted.
