What does the term "signal integrity" refer to in electronics?

The term "signal integrity" refers to the quality of an electrical signal as it travels through a circuit or system. It encompasses various aspects such as the amplitude, timing, and waveform shape of the signal, which can be affected by factors like noise, crosstalk, reflections, and attenuation. Ensuring good signal integrity is crucial for the proper functioning of electronic devices, especially in high-speed applications, where any degradation of the signal can lead to errors and malfunctions. Signal integrity analysis is a critical process in the design and testing of circuits to ensure that signals maintain their intended characteristics throughout their intended paths.
