EMC Concepts Explained

This is the first of the three articles devoted to the Smith Chart and the calculations of the input impedance to a lossless transmission line.

This is the third of the three tutorial articles devoted to the frequency-domain analysis of a lossless transmission line.

This is the second of the three tutorial articles devoted to the frequency-domain analysis of a lossless transmission line. This article shows numerous methods of calculating the voltage, current, and input impedance at various locations on the transmission line, using the Circuit Model.

This tutorial article is a part of the three-article series devoted to the frequency-domain analysis of a lossless transmission line.

This article introduces a concept of a phasor which is extensively used in several EMC topics including electromagnetic waves, antennas, and transmission lines.

This article discusses the impact of a shunt inductive discontinuity along the line as well as the effect of feeding two transmission lines in parallel. The analytical results are verified through the HyperLynx simulations and laboratory measurements.

This article discusses the reflections on a transmission line at a shunt resistive and capacitive discontinuity along the line.

This article addresses the impact of driver, HDMI cable, and receiver on signal quality using data eye, based on the following criteria: data eye opening, data mask violation, and data jitter.

This is the first of two articles devoted to an eye diagram. In this article, the fundamental definitions and concepts are presented.

This month’s column is the last of three parts devoted to designing, testing, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.
