One of the technological tools most used to interact with dynamical processes are the digital filters, which work for different utilities as: the error elimination of a system, get specific data, reconstruct and predict the system operation. Digital filters have many applications to use in many systems: control, medicine, instrumentation, electronics, computation and communications. The filter technological systems are designed to be developed with capacities as the ability to follow a process in a natural way. In the real life we can find systems with dynamical operation that requires technological applications with expert mechanisms into its internal construction in order to give answers dynamically to the different operation states of a system, moreover, having a characterization of it into its own filter structure and using an inference mechanism to select the correct response to perform a system trajectory from a previous condition to a balance state with the interaction process. Actually, the digital filters systems have many developing topic areas; therefore the study about this topic is important. The characterization of a filter responses and the inference mechanism in order to allow us to find a correct action at each time is one of the requirements to solve in order to apply the digital filters in the future into systems with more advanced properties related with mobility, velocity, interoperability, integration. Based in the previous paragraphs this project is a study of digital filters systems, considering to apply an adaptive filtering techniques, because it has important elements that will give advantages as: the possibility to adjust its parameters automatically, the capacity to have high convergence levels. Meanwhile, in a parallel way this study contains topics as fuzzy logic and real time systems, which will be useful to develop the theory of this project titled: "real-time fuzzy digital filter".
