  • Abstract
    A method is given for establishing the describing functions and transfer function for a servomechanism with saturation and hysteresis nonlinearities. This method makes use of a technique given by V. B. Haas, Jr. (in a personal communication to the authors) in measuring the phase and amplitude of the first harmonic of the system output with respect to a sinusoidal input.
