FreeLists / si-list / [SI-LIST] Differential signaling history

["Zhou, Xingling (Mick)" <xlzhou@xxxxxxxxx>]

Hi,

I am curious about the history of differential signaling. We can easily =
explain in various versions intuitively or mathematically the benefits =
of differential signaling now either in circuit design (differential =
amplifiers/also called differential pair, for example) or in PCB design =
(differential pairs), even in cable designs.  What the first guys who =
came up this idea originally thought and how/when they implemented the =
idea ?  etc.

Thanks for advice,

Mick
