Query: Krawtchouk transforms and Convolutions   We put together the ingredients for an efficient operator calculus based on
Krawtchouk polynomials, including Krawtchouk transforms and corresponding
convolution structure which provide an inherently discrete alternative to
Fourier analysis. In this paper, we present the theoretical aspects and some
basic examples.
