This article reviews the decibel units used in EMC laboratory measurements and testing. We begin by defining a decibel (dB) unit and proceed to the EMC specific units for voltage, current, power, and impedance measurements.
This article investigates the impedance of the three standard passive circuit components (R, L, and C) as well as the frequency response of a PCB trace.
This part II of the s-parameter tutorial presents several examples of the s-parameter use in EMC measurements and testing.
In this article we investigate the frequency behavior of a ceramic capacitor.
For common-impedance coupling to occur, two circuits must share a current path (with a non-negligible impedance)
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 two-sided PCB with a single trace on top and full copper ground plane on the bottom.
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.
