Abstract :
The paper presents the development and analysis of a narrowband adaptive noise equalizer (ANE), which can either amplify or attenuate narrowband noise. The output of the ANE system contains residual narrowband components, the amplitudes of which can be linearly and arbitrarily controlled by adjusting the gain parameter of the equalizer, thus providing the desired noise shaping capability. The characteristics of the ANE system are analyzed and applied to active noise control
