Summary |
A new paradigm for Sigma Delta modulators, named bit-flipping, has been developed and preliminary studies made. This project will develop these studies by examining the new architectures in greater detail. This will involve the development of new theory associated with stability of Sigma delta modulators (with and without bit-flipping), which will lead to parameterisable modulators, characterised in a similar fashion to operational amplifiers.
The project will study by simulation and emulation, various applications of the new architecture. This includes: compression of Sigma Delta encoded signals for digital Versative Disk, Signal processing of Sigma Delta bitstream & data hiding in Sigma bitstreams.
The project will provide important new results on stability of modulators, enabling them to be used by non-experts in a manner akin to the use operational amplifiers. It will further provide important results on the various applications, most of which are relevant to Multimedia Technology.
