[edit] Misleading Statements

"SE is the SCSI standard" is not entirely correct, given that SCSI-3 SPI-2 (i.e. Ultra2, etc. SCSI) introduced Low-voltage differential (LVD) signaling. --AlastairIrvine (talk) 14:59, 12 December 2007 (UTC)

[edit] Odd statement

re single ended transmission... "This technique is less expensive to implement, but its limitations are that the signal cannot be transmitted over long distances or quickly"

I dont know why the writer thought that. Several GHz can be transmitted, and routinely is using stripboard and co-ax. As for distances, even in the 1800s single ended phone circuits were working distances amounting to a sizeable percentage of the US, ie 1000s of miles. So I'll remove the above statement.

"SE is the SCSI standard, and viable cable lengths range from 1.5 meters to 3 meters."

... however the very short length limit has little to do with its single endedness.

crosstalk.... "This limits the bandwidth of single-ended signalling systems."

only in some cases, mainly where multiple parallel circuits are fed down ribbon cable and very high speeds are being attempted. For many apps its not the limiting factor at all, and makes no difference to circuit bandwidth. Tabby (talk) 22:33, 15 May 2008 (UTC)
