# Recent Advances in Variable Digital Filters

@inproceedings{Koshita2018RecentAI, title={Recent Advances in Variable Digital Filters}, author={Shunsuke Koshita and Masahide Abe and Masayuki Kawamata}, year={2018} }

Variable digital filters are widely used in a number of applications of signal processing because of their capability of self-tuning frequency characteristics such as the cutoff frequency and the bandwidth. This chapter introduces recent advances on variable digital filters, focusing on the problems of design and realization, and application to adaptive filtering. In the topic on design and realization, we address two major approaches: one is the frequency transformation and the other is the… Expand
