Signal integrity is a branch of electrical engineering that deals with the study and control of the quality of a signal as it travels through a transmission medium. It is concerned with the preservation of the signal's shape, amplitude, and timing characteristics.

Why is Signal Integrity Important?

Signal integrity is important because it can affect the performance and reliability of electronic systems. Poor signal integrity can lead to data errors, system crashes, and even equipment damage. In high-speed and high-density electronic systems, signal integrity is especially critical.

How to Improve Signal Integrity

There are a number of techniques that can be used to improve signal integrity. These techniques include:
