Abstract : In chapter 1 the list of bibliography on ferroresonance given in Technical Note No. 1 has been extended to sixty-five papers. Chapter 2 is devoted to the tests carried out on ferrite materials, the reduction of the size of cores, and the obtention of shapes more convenient for use in ferroresonance at frequencies up to ten megacycles. In chapter 3 the ferroresonant devices are described. With the series circuit without polarization as a basis, complete systems of circuit logic have been developed. The delay unit, the half-adder, a serial full adder, and some other circuits which make use of the operating principles of the delay unit and half-adder, are described. The experimental results presented have been obtained with a carrier frequency of two megacycles, and pulse repetition rates ranging between 200.000 and 300.000 pulses per second.
