Digital computer design of pulse transformers

The development of pulsed radar created a need for a relatively new type of transformer, one that transforms the energy in a pulse with an approximately rectangular shape and a time duration in the order of microseconds.1 A good deal of experimental work has been done in this field, which has evolved a trial and error method of designing pulse transformers.1¿3 This method is tedious and time consuming since it involves the use of many interdependent mathematical calculations and the necessity of making these same calculations over and over again before a satisfactory design is obtained.
