Claimed OU circuit of Rosemary Ainslie

I guess we'll have to agree to disagree Hoppy 

It not only makes the most sense, but I've proven it two ways. Also, keep in mind that all wiring impedance must be taken into consideration with this type of pulsed current.

In the real scope shots, the rise time of the Drain spike is about 50ns, which represents a bandwidth of about 7MHz. At this frequency, the reactance of a 1uH wire is about 44 Ohms, which is more than enough to allow a significant voltage bump when measuring at the Load Resistor. The same goes for oddities being observed on the shunt resistor (which is why it is critical to use one that is non-inductive).

Sorry to jump in, and this is the 1st post to read in past day, but unless it's a perfect sine wave, then there are harmonics. There would easily be considerable harmonics in the hundreds of MHz.

Don't forget that inductors have parallel capacitance, and usually a good amount.

Rosie it's been great to have you here and I hope you will stick around,
the forum needs all the help it can get to discover OU

Hi Cat. I rescued this post from 5 pages back?  Somehow I entirely missed it.  The link, as always - PRICELESS.  LOL.  Nice to know that some appreciate my input.  But you're an ever increasing minority.  It seems that MH has bowed out and Poynt's departure looms.  Personally I think that they will both stay around long enough to discover if our data meets the stringent demands of this claim of ours.  And irrepressibility of the former is only matched by the obsessive denial of the latter.

But the 'fun' part is getting seriously compromised.  Thankfully we can always rely on your own input.   The password here is 'open mindedness'.  Easily forgotten.

Hi Rosie
open minds need feeding, feed them OU and they will be back with a vengeance. 
I hope you take the opportunity to look round the forum.
As I know you enjoy British comedy, here is a modern classic.

Hi Cat.   I might tell you that you're a genius at finding good links.  I got lost on the trail of the last one and now - almost 1.5 hours later I'm back on the thread. 

Ta muchly.  I think the need for laughter is a really serious requirement.  LOL
