You dont know what you are talking about... Coils and capacitors are derivative function... The faster the voltage peak or voltage drop the bigger spike....

Square waves makes 100% sense ... dont spread this noobiness here it has nothing do to with the input signal...

Hi Kenisis,

Have you see this video of Sirhoax?
It shows the resonance you are looking for:

sorry stevie this is no where near what i'm looking for.

as a side note INDUCTIVE REACTANCE MUST BE LARGER THAN CAPACITIVE REACTANCE (Xl > Xc).......SIMPLE AS THAT....the equations listed in the beginning of the tech brief are the heart to building the vic.

first off the Z series equation is backwards......Xl comes before Xc......i encourage you to read teh book electric circuits and machines 5th edition by Eugene C. Lister

this is why stan states Impedance must be larger than Capacitance.....which had alot of us saying (you can't compare henries to farads!)....but its the reactance of impedance must be larger than the reactance of capacitance .

this second section of equations will give you the level of voltage range you are looking for.

i always hated when people would start using complex terms and throwing around equations and saying reatance, impedance, and inductance all in one sentence......but take the time to learn these concepts and it will greatly benefit you......i am buying a spectrum analyzer soon.....i feel my ferrite core in my bifilar has a frequency outside what i have been tampering with.

why? According to the tech brief Xc should be larger than Xl to make Z positive (even if i do not understand why there is a - instead of a +).

no see i said that the equation is backwards it's Xl-Xc.....look at any Z series equation....it is a typo in the tech brief......then the equation will make sense with what stanley said....look up Z series impedance.....grab the book i recommened from a library....all the answers are there.

Thats very very very nice!
I am jelious!
When do you get it?

That looks like a very nice christmas gift to me...
