There has been need in several fields of electrical engineering research for a means to study time relations, waveforms, and similar phenomena where only infinitesimal currents are obtainable. The limitations and advantages of several possible methods of investigation are compared briefly, and the conclusion reached that the ordinary oscillograph can be… CONTINUE READING
