The way to implement an ANC system by a single chip

摘要

This work develops an ANC system by using a low-cost single chip processor. In general, the processing speed of a single chip processor is low; meanwhile, a single chip processor can only do simple mathematical instructions, such as addition, subtraction, multiplication and division. A novel ANC algorithm; especially the methodology to save the computing load of ANC, is described in this paper to illustrate its effectiveness. Experimental results show that the proposed approach can be implemented by a low-cost single chip successfully and remove disturbing noise very well.
