Thank you VWestlife! I do miss that lab sometimes, and we'll get another set up soon enough! Thanks for the idea, and thanks for watching!

Thank you Alex!

HI Dave, Thanks for watching! I'm glad you liked our video about Ferrite Beads. :) I agree - they are very underrated.

Thank you Paul! I'm glad you found the channel too! Welcome!

Hello Nuno! Thank you for the encouragement, it truly means a lot. I'm glad you enjoyed our video, and I'm glad you found it helpful. I hope to see you around the comments more often, and thanks for watching!

Hello eMpTy, thanks for the encouragement!

Thank you Daniel, welcome!!!

Oof. Dirty Diesel, that's a hard question! If you're just debugging, it's totally fine to short out that bead out. They block high frequency, and pass lower ones, so everything should power up.. but you might hear some noise. Once it's powered up, if you can measure the noise frequency getting through, pick a Ferrite bead with a high impendence at that frequency! (and enough current capability) That won't get you an identical ferrite... but it should get you a ferrite that will get you back up and running!

Thank you Proje!

Thank you William!

Aaah, yes, I think I understand what I meant, and why how I explained it is confusing. So, there's a great article from analog devices that shows the frequency response (www.analog.com/en/analog-dialogue/articles/ferrite-beads-demystified.html) I think that graph may help a lot. Ferrite beads are generally used to pass DC (or lower frequencies) and block higher frequencies, so it's important to choose a ferrite bead with a significant impedance at whatever higher frequencies are being targeted. However, there is a limit to this, because at very high frequencies a ferrite bead's effective resistance starts to drop again. So, there are very high frequencies that will get through a ferrite bead, but that is why there are many different beads available, with different operating frequencies. I hope this helps, and thanks for watching!

@@EEforEveryone , perfect. That clarifies it for me. Thank you for this video and everything that you do.

Hi Arthur! Perhaps, Sometimes the radio get's picked up in a few different parts of an audio system... the audio cable is a common culprit. Also, apparently there's some malware floating around these days that plays random radio stations. It might be worth a scan, or seeing if the problem still exists with a phone or MP3 player connected!

Hello Edwin! Great question, and thanks for watching! Ferrite beads, in general, allow low frequencies to flow (like DC power) while restricting the flow of higher frequencies. This can help to prevent noise from getting into sensitive circuits, or noise from getting off of a circut board and into cables. They are very important when designing products, and can be a cheap way to improve the EMC or electromagnetic compatibility of a design. Here's some more info: www.analog.com/en/analog-dialogue/articles/ferrite-beads-demystified.html# I hope this helps!

@@EEforEveryone thank you ..... its about my scooter ..i saw some youtube DIYs ... about the ignition coil ... im planning/experimenting w/ the lowest resistance cables + spark plugs + spark plug cup ...a DIY video says that having low resistance components will give better electrical flow ....the problem is it will create EMC that will affect other electronics on my bike ... do ferrite bead really help? ... some videos claims that ferrite bead directly boost electricity current .... is it true?

@@edwindelfin7894 Hi Edwin, Ferrite beads can reduce high frequency noise. They won't boost current, or anything like that. They're like a resistor, but the resistance changes with frequency. If you truly want maximum current, then adding anything to the circuit will reduce or restrict flow. Filtering, however, is usually worthwhile.

Hello 3! You're right.. I was getting a little too focused on the screen. Don't worry, I'll never stop trying to improve!
