Re: Tesla Coil RF Transmitter

"Excellent point, and a good example of a frequency selective system
that's band limited.
Hmm, though, can one create an arbitrarily sharp cutoff with only
RC?  I think not, off the top of my head."

	We used to have a guy at Hughes named Lou Weinberg who had the
reputation of being a real expert on network synthesis.  I heard him say
that, using only PASSIVE RC circuits, it was possible to synthesize any
transfer function shape if the loss were allowed to be arbitrarily
large.  Don't know if it's true or not.  Certainly with a little
feedback you can get arbitrarily sharp response.
