| Research Abstract |
Conversion technics from a high-resolution signal to a low-resolution high-rate signal reserving precise accuracy are developed. As the low-resolution signals, the pulse width modulated signal with a discrete width and the pulse density modulated signal are dealt with. As applications for the pulse width modulation, a modulation method spreading its spectrum keeping the conversion accuracy and an extremely precise modulation method for transient signals are developed. As an application for the pulse width modulation, an approach to enlarge the operating region is proposed.
