Between WEEE, RoHS, REACH and other environmental directives, regulatory compliance labels for handling and disposing of certain products is less intuitive than it seems.

We are proud to carry on the tradition of sharing Banana Skins for the purpose of promoting education for EMI/EMC engineers.

Let's talk about flexible absorbing materials used for radio frequency (RF) noise suppression and EMC shielding in electronic products such as cell phones, MP3 players, and rugged handheld devices.

Many real-time spectrum analyzer solution providers provide in-one-instrument add-ons which allow users to perform both the traditional swept-mode measurements in addition to real-time measurements.

This article discusses CMOS inverter switching and shows the impact of a decoupling capacitor on the power rail signal integrity and radiated emissions.

TLP ideas are helpful in understanding CDE, but it is an imperfect analogy

The Banana Skin columns were compiled by Keith Armstrong, of Cherry Clough Consultants Ltd.

This article provides insight into how shielding is used in product development, in particular the effectiveness of shielding when it is applied at the PCB level. 

This article discusses the creation of a common-mode current in a typical circuit and explains the effectiveness of a common-mode choke on differential-mode and common-mode currents.

When measuring signals in electronic circuits some times what you see on the screen is not what you have in the circuit. Parasitic couplings, mismatching, noise pickup, and many other anomalous effects can give you the wrong picture of your problem.
