基于模型设计的信息噪声剔除
Model based design for noise removal
摘要
Abstract
8 This paper keeps attention on the idea of the Model-Based Design and proposes a efficient and economical approach for designing a new stop-band filter. To making full use of the resources in Matlab/Simulink, works like the audio's spectrum analysis, filter parameters' selection, stop-band filter model's creation, functional verification, HDL code's automatic generation, Modelsim simulation, and the subjective and objective evaluation of stop-band fil ter can all be achieved in the visible virtual platform. From design concepts to hardware realization, the whole process is finished in one way and every step tightly connects with each other. This paper certificates and validates filter's performance from three levels to make sure that the band-stop filter designed by this way has a good result both in spectrum displaying and subjective evaluation by ears. The filter designed in this paper can be taken as an i deal band-stop filter example and can be helpful for digital filter design.关键词
