The uniqueness in designing multidimensional causal recursive digital filters possessing magnitude hyperspherical symmetry

It is shown that magnitude hyperspherically symmetric transfer functions of multidimensional (MD) causal recursive digital filters must have numerator and denominator polynomials that are separately magnitude hyperspherically symmetric. Further, the exact reference-domain magnitude hyperspherically...
