Approximate experimental method for the analysis of EMF waves
Year: 1909
Experiments were undertaken to determine whether it is possible to get an approximate value of the first and second harmonics present in an e.m,f. wave by means of ordinary portable instruments and calibrated condensers, The author concludes that the accuracy of the method is intermediate between that of the curve tracer and that of the oscillograph, and may be taken as 2 or 3 per cent, of the fundamental. It has the disadvantage of giving no idea of the phase relations, and hence of the form factor, and of not lending itself to the analysis of current-waves, unless a considerable amount of energy is available. Its chief advantages are that no special appar
