Abstract
The present invention includes a data compression system which implements transformation and quantization functions using analog devites. The system includes a transformation module with analog devices (22), a quantization module with analog devices (24) and an entropy coding module (26). A data decompression system which implements inverse transformation and inverse quantization functions using analog devices is also shown.
