Stability and sensitivity analyses for diffusers with single and multiple active elements

Avis, MR; Xiao, L; Cox, TJ

Abstract

In comparison to active absorbers, active diffusers have more complicated target impedance functions, a smaller region of stable control, and are more sensitive to control impedance errors. The issues of stability and sensitivity are analyzed theoretically and empirically. Measurements show comparable performance for active and passive diffusers with the active solution requiring less space.
