A new method of generating functions

As a result of a pressing need for function generators, a new method of function generation has been developed. The underlying principle of this function generator is the application of ordinary pulse techniques in such a way as to produce a function. The simplicity of design, the high accuracy attainable, the simple type of construction are the outstanding features of this general-purpose function generator. In order to compare this new type of function generator with those presently being used, three important types are discussed. These generators are of the general-purpose, electric and photoelectric types; other comparable electromechanical types are excluded.¹
