The analysis of complex wave forms taken from different alternators and transformers in the electrical engineering laboratory at Virginia Polytechnic Institute

Since the work that the writer was engaged in was primarily concerned with finding the equations of the different wave forms and not in the results of what caused distortions in the wave suggestions may be offered in the way of advice to following investigators by the following remarks: (1) Observe the general shape of curve and from this count the number of ups and downs in it and from this determine how many harmonics it contains. (2) When harmonics are limited in number, use the Fisher Hinnen method or even if the harmonics are not limited in number if a calculating machine or a slide rule is not available. (3) When a calculating machine is available, use the mean value method but carry as many multiplications and summations as possible in the machine before clearing.
