Bill pointed out that communication interfaces have used AC termination for
years. Perhaps. They have at least used AC coupling. In order to use or allow
AC coupling without severe problems they also put a priority on the use of
balanced transmission codes. In order to use inexpensive cabling and in some
cases unshielded twisted pair at 100 mega transfers per second, they also use
scrambling techniques which greatly reduce the EMI emission problems.
Is there data on the impact of unbounded balance from near d.c. to 40 Mb/S of a
SCSI data transmission?
