Abstract :
The definition and development of a modified discrete describing function, referred to as dual input discrete describing function, is considered. High-frequency signal is injected into the non-linearity to quench the limit cycles in closed-loop autonomous relay-type sampled-data systems. An analytic procedure is described, which aims at deriving the dual input discrete describing function for a relay in the 
domain.
