Abstract :
The authors give structures realizing first- and second-order, separable, 2-D, all-pass digital filters. The method employs signal flow graph technique and S.J. Mason´s gain formula to obtain the transfer function. The realizations obtained are minimal delay and minimal multiplier structures
