Development and analysis of optimized narrowband ANC systems
(Northern Illinois University, 1995)
In this thesis, the research on narrowband active noise control (ANC) systems is presented. The effect of the secondary path transfer function on the convergence of the filtered-x least mean-square (FXLMS) algorithm is ...
Development of an adaptive delay filter for active periodic noise control
(Northern Illinois University, 1994)
An adaptive delay filter (ADF) for active periodic noise control (APNC) system has been developed in this thesis. An ADF consists of one variable delay and gain, which has the benefit of simplicity that saves computational ...
Development and analysis of delayed-X LMS algorithm for active periodic noise control
(Northern Illinois University, 1992)
The conventional adaptive notch filter uses two single tap Finite Impulse Response (FIR) filters and a 90 degree phase shift unit to cancel narrow-band noise. In this thesis, a new adaptive notch filter, which uses a ...
