| Abstract(in English) | This paper proposes a design method of high accuracy 2-D variable IIR digital filters. In this proposed method, a parallel allpass structure with complex coefficients is used as a prototype structure. The parallel allpass structure is derived from the 2-D separable-denominator transfer function. The coefficient sensitivity of each complex allpass structure is reduced to improve frequency tuning accuracy of the 2-D variable digital filter. By reducing the coefficient sensitivity of the filter structure, the high accuracy 2-D variable digital filter is implemented. Numercal examples show that the tuning accuracy of the proposed variable filter is higher than that of the conventional variable filter under limited coefficient word length. |
