Abstract
This article presents a simple way to construct a pair of quasi-linear-phase bandpass filters that have identical magnitude responses and differ in phase by 90deg that can be used for analytic signal generation. Furthermore, these filters have useful symmetry properties that significantly reduce their computational complexity and coefficient storage requirements, and there is no inherent length limitation to the size of the filters.
