Ferrite Core Basics - Your Circuit Impedance Matters More than You Think 

Thanks for the demonstration that the attenuation property of a ferrite choke depends on the circuit's impedance in which it is employed. As an amateur radio operator, I was all the time have been made aware of the choking impedance of various ferrite mixes in a 50 ohm environment. I'm looking forward to the next episode of the effect of interwindig capacitance and how to avoid it in the construction of a ferrite choke. I hope that will be accomplished by spacing the windings on the perimeter of the torroid core. De VU2RZA

Excellent video

Not able to download the paper from website

These days people watch videos at 1.5-2.5x speed, coupled with camera motion it creates a terrible viewing experience.
