| Abstract(in English) | As a digital modeling method for effect pedals and amplifiers, the best approach is a method of converting an analog circuits to a digital mathematical model as it is. However, this method has a problem that the modeling cost is very high because it is necessary to accurately investigate circuits using reverse engineering and model the characteristics of their elements. In conventional researches, a method of suppressing the cost for modeling has been proposed by dividing the components of the distortion circuits into linear blocks and nonlinear blocks and modeling nonlinear blocks by adaptive signal processing as black boxes. However, this method does not have high accuracy and its extensibility also remains. In this paper, we implement this method and discuss its accuracy and extensibility. |
