Description
Tree- structure NSDEM method has been proposed as a method to suppress and reduce the increase in circuit size due to the number of processing bits in a digitally direct driven speaker.In this study, we applied this tree structure NSDEM to a directivity speaker system using digitally direct drive method, and simulation and actual measurement are carried out and the results are presented.Key Words : Digitally Direct Driven Speaker(DDDS) , NSDEM, Directivity Speaker ,amplitude control, tree structure NSDEM
