Hi Jerome, >> No, it never leak! That bit was a joke - honest !
>> The signal propagates along the line, and when it reach the end of the line, >> it partially reflect (just like waves do on harbour) and then propagate back, >> crossing the new incoming signal... This is what confuses my simple brain, in order for a reflection there should be 'something' at the end to reflect back off of. If there is nothing to reflect from then there shouldn't be a reflection. Using your harbour analogy, there is a harbour wall to reflect back off whereas in an unterminated cable, there is nothing. (Did I mention that I wasn't all that good with hardware ?) <SNIP> >> Single wire are not so nice, hence the need to correctly terminate the line >> with device or a resistor. So how does having a resistor stop reflections then - and how do you pick a correct value, Tony mentioned 330R what's so special aboput that value ? (My knowlege here extents to V=IR). Cheers, Norman.
