Ferrite cores are often placed on cables to suppress the common mode noises so that radiation can be suppressed. Experienced engineers would know the suitable materials to do the job deeding on the frequency range of interests. But where to place a Ferrite core on a cable? This video demonstrates the theory behind it. For more demos like this, you can check our first video-recorded training course at mach1design-shop.fedevel.education/itemDetail.html…

    I normally don't comment on videos, but this was a great, practical demonstration - thanks for sharing!
  • @buckbrown823
    Really great video. Great effort and set-up makes it easy and practical to understand.
  • @ininjad24
    Excellent practical demonstration - seeing is believing! The FFT analysis of square wave with fast switching could be included to demonstrate the harmonic spectrum. In real life, inserting ferrites is a post-facto treatment. Do consider making making videos where filters are introduced during the design stage.

    Great demonstration. Seeing is believing
  • @sparqqling
    Great video, perfect demonstration of the principles at play and concise in just 7 minutes. Hats off, that's not easy! Click bait title would be nice, most people do this wrong 20dB attenuation with a ferrite bead.

    I love this. RF should not be black magic. Keep up the good work!
