ABSTRACT:
A method of and apparatus for converting between first and second digital data formats is disclosed whereby digital words of the first format are analyzed to detect an upper bandwidth limit of a corresponding analog signal in an interval thereof defined by such words and to determine the level of the analog signal at the beginning of such interval. A digital word of the second format is encoded with first and second pluralities of bits representing the determined upper bandwidth limit and the level of the corresponding analog signal at the beginning of the interval.
