Hence, with this ideal adjustment of the couplings, thereceiving efficiency of the anti-sidetone circuit will be the same asthat of its sidetone complement. Although equally satisfactory designs could be worked out withother polings of the coil windings, the relative inductive directionsamong windings A, B and C in the circuit here dealt with are suchthat, if a current were passed through all three in series, windingsA and B would be inductively aiding; and C would be inductivelyopposed to both A and B. Returning to the above condition formaintaining the receiving efficiency, namely, that /g^ be made zero,the windings of the coil must be so adjusted that the sum of thetwo voltages induced in winding C by its inductive couplings withwindings A and B is equal and opposite t
