The use of gradient-based algorithms with infinite impulse response (IIR) notch filtering for
estimating sinusoids imbedded in noise is investigated. Two notch filter model structures are …

The spectral line analysis (SLA), also called line spectrum analysis, deals with the problem
of extracting information on sinusoidal signals from noise-corrupted measurements. It has …

The conditions required to implement real-time adaptive prediction filters that provide nearly
optimal performance in realistic input conditions are delineated. The effects of signal …

Rotating machines such as motors, generate noise at the fundamental frequency and its
harmonics. The narrowband active noise control (NANC) algorithm is widely used to cancel …

This work examines the performance of both offline and online secondary path modeling
algorithms that are used in narrowband active noise control (NANC) systems. Theoretical …

Narrowband active noise control (ANC) systems have many real-life applications where the
noise signals generated by rotating machines are modeled as sinusoidal signals in additive …

The acoustic environment in an automobile cabin has a significant effect on the perceived
quality of the vehicle. There are two components of the acoustic environment in the …

The frequency of an internal synthetic reference signal that is inconsistent with that of the
noise signal is a serious problem in narrowband active noise control (NANC) system. This is …
