BUS TERMINATOR HOW IT WORKS ???

[Sakthi vel]

I know Terminators are used to avoid signal bounce in the BUS topology but I want to understand how the signal bounce can happen in Bus topology.

Please help me to understand clearly with technical notes.. you can post on Electronics terms also to understand

Regards,

My understanding, the signal bounces (or reflects) off the end of the physical "wire".  A terminator dampens the reflection.

Hi Joseph,

I Understand signal Bounces at the end of the wire, But why it bounces... I'm not able to get the answer for this anywhere.

Physics.  The signal wave "sees" the end of the wire as a "wall" and will reflect off it

Drop a coin it a pot of water and you'll see the waves reflect off the pot's sides.  Same principle, I believe.
