CIRCULAR CONVOLUTION AND FOURIER DISCRETE TRANSFORMATION

We present the discrete circular convolution and its algorithms of calculus. Using discrete Fourier transform can be determined the circular deconvolution, ie the circular convolution inverse. We exemplify these concepts by solving an equation of circular convolution. This type of convolution product is applies to the periodic phenomena, discretely analyzed. By this paper we continue the series of articles about the types of discrete convolution products and their applications, some of which being cited in the References.
