Sinais e sistemas definidos sobre aritmética intervalar complexa

in this work, is made the reasoning for the concepts of interval complex signs and systems, making the use of rectangular complex arithmetic and the concept of interval complexes numbers made ??with the help of kulisch-miranker order to complex. it is also presented the concept of interval representation and the canonical interval representation (cir) to complex functions. from a system f which operates on signals whose values ??are complex numbers, by using the cir, is found a interval system f which preserves, in the interval sense, the properties of f, such as stability, time invariance, additivity, homogeneity and linearity.
