Parallel-form narrowband feedback active noise control (FBANC) system has been shown to perform better than conventional internal model control (IMC) based FBANC system in cancelling multi-tonal noise. A previous paper illustrated a novel approach in estimating the frequencies of the multi-tone noise, and using an internal tonal generator cum frequency grouping unit to increase its frequency separation in each channel of the parallel-form FBANC system based on a full-band error. This paper investigates whether it is necessary to use a narrowband error to further improve on the performance of the parallel-form narrowband FBANC through theoretical analysis. Computer simulations are also presented to validate its performance.
