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.

When routing a printed circuit board (PCB), try to avoid critical signals in emissions or immunity close to the edge of the board to create a more robust system for EMI and EMC.

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.

Low-cost designs are often an underserved and challenging part of a layout engineer’s career and getting increasingly complicated.

The mirror technique is a very old technique to be used with PCBs when failing in radiated EMC tests. An easy solution to avoid changes in layout if the technique can be applied to your product.

This article discusses the crosstalk reduction between PCB traces by utilizing a guard trace between the traces and investigating the effect of the guard trace grounding.

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

Software tools can give the EMC engineer a better chance to pass EMC requirements the first time.

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.

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.
