Comments on 'Synthesis of spectrum shaping digital filters of recursive design'
Abstract
The problem of designing recursive digital filters can be reduced to polynomial approximation on a finite interval. The procedure to demonstrate this equivalence described in a recent paper yielded filters with multiple poles. An alternative method is described which avoids this restriction.
