As the positive alternation is interruptedat points off the peak, a smaller amount of negative current and a larger amount of positivecurrent will be admitted and the net result of this will be a decrease of telephone currentas the zero axis (Fig. 298a) is approached. When the interruption of the incoming oscillation takes place at the zero axis, equalamounts of positive and negative current (G and G-1, Fig. 298a) will be admitted to the telephone and there willbe no deflection of thetelephone diaphragm. Asthe interruptions con-tinue beyond this point,positive current of grad-ually increasing strengthwill be admitted to thetelephone until the fullamount of positive cur-rent flows. There is thusseen to flow through thetelephone, an audio-frequent current which rises, falls and reverses uniformly at a frequencywhich is the numerical difference of the inter
