Resumo

This study conducts an introductory investigation of the Fourier series with fuzzy coefficients. A structure of Hilbert space is provided throughout an identification of the convergent square summable real sequences into a set generated by an enumerable family of strongly linearly independent subsets of fuzzy numbers. An application to a signal processing model with the fuzzy Fourier series approximation of the square wave is presented.
