*k* = (*f*_{h}^{2} – *f*_{l}^{2}) / (*f*_{h}^{2} + *f*_{l}^{2})

where

*f*_{h} is the higher resonance frequency and

*f*_{l} is the lower resonance frequency

Note 1 to entry: The coupling is mainly made either magnetically or electrically which is called magnetic or electric coupling, respectively.
