Discussion on “form factor and its significance” (Bedell, Bown, Pidgeon), “distortion factors” (Bedell, Bown, Swisher), and “an analytical and graphical solution for non-sinusoidal alternating currents” (Mizushi),

Joint Committee on Inductive Interference (communicated): Apropos of the present general consideration of irregular waveforms, this committee desires to call attention to an important aspect of this subject which has not hitherto received the attention which it merits. The interest of this committee in this matter arises from its bearing upon the subject of the committee´s investigation — inductive interference. It is not overstating the facts to say that were it not for the irregularities of waveform of common occurrence in power circuits, the necessity for the formation of a committee of this character would not in all probability have as yet arisen. There is a strong presumption that the difficulties not arising from irregularities of wave form could have been overcome without the medium of such a committee.
