| Summary: | Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2005. === Includes bibliographical references (p. 63). === Systems are often restricted to have higher transmission frequency than required by their data rates. Possible constraints include channel attenuation, power requirements, and backward compatibility. As a result these systems have unused band- width, leading to inefficient use of power. In this thesis, I propose to slow the internal operating frequency of a cochlear implant receiver in order to reduce the internal power consumption by more than a factor of ten. I have created a new data encoding scheme, called "N-[pi] Shift Encoding", which makes clock division a viable solution. This clock division technique can be applied to other similarly constrained systems. === by Andrew D. Selbst. === M.Eng.
