Subject: Is it possible to create Resonance with DC impulses ?

It is said that Nikola Tesla used impulses instead of alternations in some of 
his circuits and achieved resonance. My question is, if I can create a 
resonance effect on my RLC circuit, when I apply pulsed dc (rectified AC or 
square wave for example) with a function generator ? Why ?
Tesla believed that dc pulses were much better than ac (alternations)!

Is it also possible to create such impulses by recharging a bank of capacitors 
as Nikola Tesla did ? Why ?

I plan to use a function generator, would rectified ac be better than square 
waves in my RLC circuit, why ? I was not able to find a resonance equation for 
dc impulses, could you help me please.

Many thanks,
Sharon
