As many circuits and applications now enter the Gigahertz frequency range, accurate digital timing measurements have become crucial in the design, verification, characterization, and application of electronic circuits.To be successful in this field an engineer needs to understand instrumentation, measurement techniques, signal integrity, jitter and timing concepts, and statistics. This book gives a compact, practice-oriented overview on all these subjects with emphasis on useable concepts and real-life guidelines.
