A symmetric digital filter. The filter has the dimensions N rows by N columns. There are a predetermined number of 8-input adders, and a predetermined number of 4-input adders each able to receive inputs from samples of an incoming signal. In addition, there are a predetermined number of parallel multipliers. The parallel multipliers receive output signals from the 8-input adders and the 4-input adders, and multiply the partial sums by coefficients of the digital filter, applying the digital filter to the input signal.
