I think you touched another point. Most of them are talking about data rate and frequency, you are talking about the field bandwith (frequency). I can not see direct relations between the two although we have a rule of thum saying that t_r ~ T/10. Where T is the period. Obviously they are different GHz with different physical meanings.

For example, if BW=3.5GHZ, then tr=0.1ns Once you get the tr, you can decide the bit rates in Gbs of the link. Hope it helps, Yibing -----Original Message----- From: joe nguyen [mailto:jooonguyen@xxxxxxxxxxx] Sent: Thursday, June 20, 2002 1:27 PM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] Ghz/Gbs convert Dear Si Expert, Just a silly question. How would you convert Ghz to Gbs? What is the rule of thumb?
