Effective reduction of compressed signal amplitude is provided when the phase of topology adjacent areas changes to 180 degrees. Physically this phase change for all areas can be achieved only by the local changes of primary signal delay time with one side of the interdigital transducer (IDT). A significant signal change at the sensor output may also be achieved under other laws of speed change of a surface acoustic wave (SAW) on the acoustic waveguide. In particular there can be used constructions in which the linear dependence of SAW velocity (Roberval parallelogram) is implemented. Stabilization algorithms of discrete control system with singleton-output are proposed. The specified system relates to control systems with logic controllers. Functioning of system is based on rules of form if - then, defining interrelation between multiple inputs and one output of studied system. The combined method of Lyapunov functions based on combined using of Lyapunov functions and properties of linear matrix inequalities is used. The obtained results can be used for the solution of problems of stability and stabilization of controlled systems with logic controllers, and also for improvement of technical control systems.
