| Abstract(in English) | Variable recursive digital filters require lower orders and less computational complexity to satisfy the same desired variable magnitude responses than finite-impulse-response (FIR) filters, but the stability of variable recursive filters is difficult to guarantee since their coefficients are also varied in some manner. This paper proposes a new method for designing variable recursive one-dimensional (1-D) filters with guaranteed stability. The basic idea is to find the coefficients of the variable transfer function as multi-dimensional (M-D) polynomials of the spectral parameters that specify variable magnitude characteristics. To guarantee the stability, we first substitute the denominator coefficients by another set of variables which can take arbitrary values without affecting the stability. Then both the numerator and the new denominator coefficients are determined as M-D polynomials of the spectral parameters. |
