Hello,

I read one of the articles by Dr.Eric Bogatin of Bogatin enterprises.

He has mentioned that the signal moves down the trace/line at the speed of light in the dielectric medium typically about

6 inches/nsec?

But there is a question why it moves so fast and is not the speed of the electrons which is closer to 1cm/sec.

Expecting your comments.

regards,

Selva
