You have a driver that drives a long signal & connects to an
input device. At the input device there is either overshoot,
undershoot or signal threshold violations, what can be done
to correct this problem?

Answer / the big boss
This is a signal integrity question for board designers.
there are two types of termination schemes viz. series and
parallel termination. series termination is where a resistor
of small value ( rule of thumb 1/2 of characteristic
impedance of the trace ) placed near the source ( near
driver). the parallel termination is a combination of two
resister ( rule of thumb twice the char. impedance f the
trace) placed near the destination ( input) where one
resistor connects the signal trace to the VCC and other
connects to the GNd.

To avoid signal threshold violations(due to loss in long
path), use repeaters to boost signal strength at spec.
