This report covers the findings of a study which was devoted to arriving at recommendations for a low-cost, small-size converter for use in the 480-L system. The investigation was concerned with conversion between Baudot and Fieldata but the technical conclusions developed are applicable to other code schemes. Several semiconductor code converter designs are presented that employ a minimum of semiconductor equipment. These designs are analyzed in terms of quantity of equipment necessary for implementation. One design, the Hybrid 2 x 4 method, is shown to be best. This design employs 50 gates using a total of 312 inputs to the gates. An analysis of parametron application to code conversion is presented, and a design method using parametrons is indicated. The design of a Baudot to Fieldata code translator using parametrons, built and tested at RCA in November, 1960 is described. An evaluation is made of the relative advantages of the best of the analyzed semiconductor and parametron designs. The parametron design was found to be less expensive, in general more flexible, and lighter and smaller in size. Author
