Performance comparisons for nonrecursive digital filters with nonlinear phase characteristics
M. A-Razzak, LAURIE G. CUTHBERT · Electronics Letters · 1978
This letter presents a comparison between the performance, in terms of ripple and transition bandwidth, of nonrecursive digital filters with arbitrary phase characteristics and those with a linear phase response. Results are given which show that filters can be designed to have an arbitrary phase response, yet give as good a gain response as filters with linear phase.
