  • Abstract
    This paper presents the analysis of narrowband active noise equalizer (ANE) with imperfect secondary path estimation. Perfect secondary path estimation is often not available in practical cases. Under imperfect estimation condition, the system convergence and equalization exhibit properties not found in past literatures. The origin of such phenomenon is investigated. The maximum step size and misequalization are examined. Simulations were conducted to verify the theoretical analysis.
