Review of active noise control algorithms for impulsive noise control
Active noise control is gaining popularity in recent years. Especially, active control of impulsive noise is of great interest. Due to specific nature of such noise, standard approach to active control is not satisfying. This paper reviews existing algorithms specifically developed for impulsive noise control. Performance of the algorithms is verified using computer simulations and several nois...
متن کاملActive Noise Control System for MR Noise
We propose an active noise control (ANC) system for reducing periodic noise generated in a high field area such as noise generated from magnetic resonance imaging (MRI) devices (MR noise). The proposed ANC system utilizes optical microphones and piezoelectric loudspeakers, because specific acoustic equipment is required to overcome the high-field problem, and consists of a head-mounted structur...
متن کاملA High Performance Feedback Active Noise Control System
In many active noise control (ANC) applications, an online secondary path modelling method that uses a white noise as a training signal is required. This paper proposes a new feedback ANC system. Here we modified both the FxLMS and the VSS-LMS algorithms to raised noise attenuation and modelling accuracy for the overall system. The proposed algorithm stops injection of the white noise at the op...

متن کاملModeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO
The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...
