This is an undesired event as the previous symbols have a similar effect as noise, affecting the reliability of the communication. Intersymbol interference (ISI) is a type of signal distortion in which one symbol interferes with consecutive symbols.

It is can also be described as a waveform, a state or significant condition in the communication channel that persists for a fixed period. These data rates have been nearing the Gigabit-per-second regime, leading to tighter timing budgets.Ī symbol can be classified as either a pulse in digital baseband transmission or a tone in passband transmission using modems in telecommunication. Data rates are increasing, pushing more bits per unit time through a single interconnect link/channel. In the constantly evolving computing field, the shift from parallel to high-speed serial-data transmission is giving rise to new PCB design challenges. Instrumentation to measure signal integrity When it comes to high-speed boards, designers need to pay attention to both analog and digital aspects of the signal. While signal integrity is not a critical issue at lower frequencies, at higher frequencies (>50MHz) it plays a vital role.

Signal integrity is the measure of the quality of the signal (signal degradation) that passes through a transmission line from a driver to a receiver.

Signal integrity (SI) indicates the signal’s ability to propagate along PCB traces without distortion. S-parameters deal with the transmission and reflection of signals for any network. This is where S-parameters come into play, as circuit/network parameters can be measured in terms of reflection and transmission coefficients.
