Fig. 6 — Normalized driving point properties of two coupled, synchronously 

 tuned resonators having equal Q's. (a) Input impedance, G\Z\, versus frequency 

 deviation from resonance, 2Q8, for various degrees of coupling, Qk. (b) Input 

 phase angle, <f>, versus frequency deviation, (c) Rate of change of <f> with 2Q5 

 versus 2Qd.
