About us

Mathematical Engineering Laboratory offers education and research on various circuits for information transmission, analog/digital signal processing, and modern digital communication systems, based on circuit theory, nonlinear theory, information theory, probability theory and communication theory. Main research topics of this laboratory are as follows: 1) analysis and design methods associated with large scale integrated circuits, 2) theoretical and experimental clarification of complicated phenomena in nonlinear circuits including neural networks as well as their application to signal processing technology, 3) construction of digital chaos systems based on nonlinear theory and their application to digital communication networks, 4) basic problems in information theory and related areas.
