   Abstract:
   A generalized procedure is presented by which the existence and stability of limit cycles can be examined in a single-loop feedback system with multiple memory-less non-linear characteristics. The method is based upon the describing function technique and has been programmed for the digital computer to handle complex and high-order systems. Nevertheless, the method is equally applicable in the absence of computational facilities. Several examples illustrate the proposed technique.
