Abstract :
Variable digital filters are especially difficult to design in the case that the given variable design specifications are complicated. This paper proposes a new method for designing variable one-dimensional (1-D) digital filters approximating both the given variable magnitude specification and the linear phase specification based on the complex array decomposition
