Abstract :
Minimum phase equalization techniques used to suppress acoustic oscillations in hearing aid systems are described. Minimum phase equalization techniques cancel a substantial fraction of the open loop phase delay and make it easy to use other techniques to suppress acoustic oscillations. Some design examples, together with computer simulation results, are presented
