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 article discusses the reflections on a transmission line at the capacitive and inductive loads.
This article uses a classical circuit-theory model of a series RLC circuit to explain the phenomenon of ringing on a transmission line, or a PCB trace.
This article explains the creation of a bounce diagram for a transmission line circuit (see  for transmission line reflections).
This s-parameters tutorial consists of two parts: Part I discusses the fundamental background needed to understand the concept of s-parameters; Part II explains the s-parameters use in EMC measurements and testing
This article examines the spread-spectrum frequency dithering technique to reduce the EMI noise from a SMPS.
In this month’s EMC Concepts Explained, we explore the conducted immunity test known as a Bulk Current Injection (BCI) test, according to ISO 11452-4 specification . This immunity test is carried out by inducin... Read More...
This article discusses a practical approach to designing an input filter to the switch-mode power supply (SMPS).
We compare the shielding effectiveness of various solid metallic shields by direct H-field measurements in the near field of the source.
