| Research Abstract |
The object of this research is to estimate a position where noise has been generated and from what it has been generated. In these two years, we have mainly researched about next three subjects. (1) To know characteristics of noise source, we investigated a generation mechanism about noises from a fluorescent light with glow switch and a lamp with touch sensor. (2) To know propagation characteristics of induced noise on communication cable, we investigated characteristics of unbalance about earth of the balanced cable and proposed a new calculation method of it. (3) For noise suppression, a common mode choke is used. We proposed an equivalent circuit of common mode choke to analyze a cable circuit including a common mode choke.
