sessential as clearness it is clear that the inductance loadingis the better solution of the problem. Sine Wave.—In order to understand Pupins theory it isnecessary to understand what is meant by a sine wave.In Fig. 402 the wave form a a a represents such a sine wave,such as may be generated by the… … Fig. 402.—Sine Wave Diagram the wave curve is plotted from the angles. Distances measuredto the right represent the time taken in making the revolution.Although telephonic speaking waves are of a very compli-cated nature, it has been found that they are all compoundedof a number of such simple sine…
