Abstract :
An approach for deriving the all-pass transfer function required to equalize the group delay of a known network transfer function or to realize an arbitrary specified delay requirement is presented. An iterative computer algorithm which is significantly simpler than previously published methods is developed for a PC, thus helping the designer to solve difficult group delay equalization problems. Some design examples are presented
