V. N. Malozemov and S. M. Masharsky Haar spectra of discrete convolutions [Abstract] In a space of discrete periodic signals, two wavelet bases related with the discrete Haar transform are considered. For expansions on these bases the analogues of the well-known shift theorem and convolution theorem are obtained.
