CIRCULAR CONVOLUTION AND FOURIER DISCRETE TRANSFORMATION

Cîrnu, Mircea Ion - In: Romanian Economic Business Review 7 (2013) 2, pp. 280-287

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 …
