In this episode, we demonstrate how the spread spectrum technique works, staying at a basic level as this topic alone could easily fill a book. For those seeking deeper expertise, we recommend Professor Bernd Deutschmann's (ieeexplore.ieee.org/author/37265457700) research group at TU Graz. Audience Level: Power electronics engineers, EMC engineers, and senior-level engineers.

This is a follow up episode based on last week's discussion. We made this based on our viewers' feedback. We extended the discussion a little bit further, including the co-axial cable.

In this episode, we showcase an intriguing setup to demonstrate loop inductance and the behavior of current along the return path. As frequency increases, the energy prefers a transmission line with a much smaller loop size, and the return current closely follows the path of the forward current. Audience Level: Designed for electronics engineers and those new to the topic.

Video Content: A concise practical demonstration video showcasing the concept of the ground/earthing lead and the loop impact. Audience Level: Designed for junior engineers and those new to the topic.

The green and yellow earthing wire is the go-to option for equipment grounding or earthing. But why is it that this seemingly harmless wire often acts as a noise culprit? In this short video, we try to demystify it. The video features Tom Dowd from Telonic telonic.co.uk , using the Microtest impedance analysertelonic.co.uk/product/microtest-6630-3-precision-high-frequency-lcr-meter-10hz-to-3mhz...

In this short video, we demonstrated the concepts of: 1. Loop inductance 2. Parallel plate capacitance 3. L-C structure circuit We then demonstrated the EMI issue (immunity in this case) which is associated with this particular structure.

Content: Should we terminate my screened cables at one end or both ends? For high-frequency, high-speed applications, it’s generally advisable to terminate the shield at both ends. This video follows up on our previous discussions, and we plan to create more episodes on shielded cables in the future. Audience Level: Electronics and mechanical engineers.

We often need both EMI filters and shielded cables for suppressing the noise. But what if you cannot design the filters inside the box? Following last episode, Quell has sent me a sample to try, it is essentially 47pF capacitors fitted to each pin, the silicone has conductive property, hence these capacitors are bypassing capacitors in essence. Watch the video and find out the performance of th...

Most shielded cables that engineers purchase from Amazon and eBay can't always be trusted. The best approach is to always verify their effectiveness. In this video, we’ll show you a simple trick to improve your cable's shielding performance. Audience Level: Electronics engineers, mechanical engineers, system engineers

We will do a short 45 minute session in Coventry, scheduled for October. This session is free to attend, see link below : www.engineeringdesignshow.co.uk/conference-programme/benchtop-emc-testing-save-time-cut-costs-ensure-compliance?&filters.date=09-Oct-2024,10-Oct-2024,&sortby=customfield_4625 asc&searchgroup=libraryentry-conference-programme

In this series, we demonstrated the shielding effectiveness of commonly seen shielded cables. This is Episode 1, where we compare the two types of shielded cables. Audience Level: electronics engineers, system integration engineers

If we want to unlock the mystery behind the limits and test methods used to control unintentional Electromagnetic Interferences, we need to re-visit the time when radios were affected by noise culprit. Many people actually don't know that the good practice we employ on EMC engineering is all about protecting radio device.
