EMC Concepts Explained

For common-impedance coupling to occur, two circuits must share a current path (with a non-negligible impedance)

This article is devoted to the radiated emissions measurements. These measurements can be performed either at the Open Area Test Site (OATS) or in an Absorber-Lined Shielded Enclosure (ALSE).

The article discusses the behavior of voltage and current waves on a transmission line with different types of loads and explains how to measure the VSWR of an antenna.

This article is devoted to the current method of the conducted emissions measurements.

This article focuses on the current probes used in EMC measurements and testing.

This article describes the voltage method of the conducted emissions measurements.

This article discusses the topology and characteristics of a dc Line Impedance Stabilization Network (LISN), often referred to as an Artificial Network (AN).

Consider a spherical capacitor consisting of two concentric, conducive spheres separated by a dielectric.

Consider a two-sided PCB with a single trace on top and full copper ground plane on the bottom.

Reducing the duty cycle (the pulsewidth) reduces the low-frequency spectral content of the waveform, but does not affect the high-frequency content.
