Abstract
The phase-equalization problem for continuous-time and discrete-time linear systems is considered from a theoretical point of view. The purpose is thus not to present an efficient algorithm for solving this problem in practice, but to offer a mathematical proof that an arbitrarily tight approximation of the linear phase behavior in any given finite frequency interval is always feasible. It is shown that the problem can be reduced to the equalization of the phase of a real first-order all-pass section. This simplified problem is investigated
