IntroductionConsider a typical configuration of the sampled-data control system.It consists of the plant to be controlled, a sampler, a discrete-time controller and a zero-order hold.Disturbance can be seen as an integral part of the plant so that the plant is characterized by the control path responsible for control signal influence on the output and the disturbance.The system output is usually sensed by sensors whose output signal can be corrupted by noise.Sometimes analog filters are put between the analog sensor output signal and sampler.In the control literature Analog Filter h Controller ZOH
