Abstract :
A method is described to realize 2-D all-pass digital filters using a minimum number of multipliers. The multiplier values are real and are obtained as simple functions of the coefficients of the transfer function. It is shown that using this method one can realize a first-order 2-D all-pass filter with only three real-gain multipliers and three delays
