Hello all,
          What is the difference between these two terminations?Why?
1)
             -----------------------
DRIVER->-----| TRANSMISSION LINE |-------------RECIEVER
             ----------------------- \
                Zo=50ohms /Rtt=50ohms
                                          \
                                          /
                                         ---GND
2)

             -----------------------
DRIVER->-----| TRANSMISSION LINE |-------------RECIEVER
             ----------------------- \
                Zo=50ohms /Rtt=50ohms
                                          \
                                          /
                                        ------TERMINATION VOLTAGE=Vtt

If signals of 5V come from drivers,no reflection will take place at the
reciever ends.Since in above two cases,way of termination is
different,what exactly the different uses of these two terminations.

Regards
Sunil
