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.

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