When two circuits are in the vicinity of one another, a signal propagating in one circuit can induce a signal in another circuit, due to capacitive (electric field) and/or inductive (magnetic field) coupling between the circuits. This phenomenon is referred to as crosstalk.
This issue’s topic is rather unique because this column addresses safety requirements for a non-safety critical device, “operational” or “functional” insulation.
As of June 13, 2017 all radio transmitters that are placed on the market in the European Union will have to comply with the new Radio Equipment Directive (RED) 2014/53/EU. This reality affects millions of devices destined for the EU.
Recast versions of the EU’s EMC and Low Voltage Directives are now in effect while the entirely new Radio Equipment Directive can also apply (it is being phased in). This article considers the requirements of each of the Directives, discussing similarities and differences between the laws.
The purpose of this article is to provide an order in the design of the electronic system such that EMC considerations can be evaluated throughout the design effort, producing an electromagnetically compatible system at a minimal cost.
This article documents the role of margin demonstration in system-level EMC testing: how and why they were first instituted, and how they have evolved over time.
It is very common for people doing simulations to make a measurement of a similar set up to validate the simulation. This is a reasonable precaution since modern simulation tools will give a very accurate answer to whatever question it is asked.
This article will discuss one of the most prolific connectors in the electrical communication field, the RJ45 connector. Most LAN cables use these connectors, so this connector touches most of our lives every day.
There are several scenarios where integrated circuits (ICs) are mounted on printed circuit boards (PCBs) which might be charged-up and experience CDM-like events.
