Crosstalk problems here to stay as long as interconnects are designed as the open waveguiding systems. Thus, understanding and proper quantification of the crosstalk and mitigation of the consequences are important. This article outlines multiple possible ways to quantify the crosstalk: coupling coefficients, frequency domain metrics, time-domain analysis of crosstalk, and a modern statistical approach. 

Intra-pair skew is a crucial metric when working with multiple lines. Its behavior, measurements, and interpretations are closely linked to other forms of signal degradation, making the definition of a single skew value a nuanced issue that requires careful consideration. In this article, Gustavo Blando and Prashant Pappu introduce three distinct methods for measuring skew, providing options for a wide variety of contexts and skew measurement goals.

Modeling and measurement of digital serial interconnects is usually done in the frequency domain. That means that the minimal and maximal frequencies (or bandwidth) should be defined even before the analysis or measurement begins. This post introduces a simple and practical way to identify the bandwidth with a numerical analysis of defects in a single bit (SBR) or single symbol response (SSR).

Few topics are as fundamental in signal integrity and create as much confusion as signal bandwidth. What exactly does bandwidth refer to and what features in the time domain influence bandwidth: rise time or slew rate?

Eric Bogatin explains the figures of merit in the time and frequency domain, and he steps through how to get a rough measure of the highest frequency components in a signal.
