The ability to give the time and quality of the signal accurately is known as 'Signal Integrity of an instrument'. Signal integrity analysis is significant for high speed PCB design due to higher clock speeds and high signal edge rates.
Since the poor signal integrity affects circuit failure, errors,multicrossing, EMC, false switching, RF emissions & reliability, hence the problems associated with signal integrity should be solved at PCB level despite system or instrument level.
Signal integrity reveals that the signal shape should perform the correction in switching & the prevent the possibilities of false switching. Therefore, several factors such as the stub length, parallel tracks, bends, planes, vias ,crosstalk and impedances affect the signal integrity in one way or the other.
