Re: Re: Frequency Splitting

Original poster: "Dr. Resonance" <resonance@xxxxxxxxxx>

The resonance points occur at two different frequencies each equidistant from the resonant peak. Maybe frequency splitting isn't the best term but two separate resonant freqs occur with overcoupling which produces two separate points along the coil when potential peaks occur. Then, these two pure freqs start "beating" against each other and standing waves occur.

If the identical tank circuits are coupled, you are correct one tank does not operate at a different frequency (single). What happens is the original resonance in both tanks are replaced by two new resonances at either side of the original frequency ie the original frequency is split in to two frequencies. Both the secondary and primary have these two new resonances.
