<p>In apparatus for selectively compensating burst errors of variable length in successive data words, correct and erroneous data words are identified, and the presence of one of the following error conditions is sensed: (a) an erroneous data word preceded and followed, respectively, by correct data words; (b) a plurality of successive erroneous data words preceded and followed, respectively, by correct data words; and (c) a predetermined number of successive erroneous data words preceded by a correct data word. These error conditions are compensated respectively as follows: (a) the erroneous data word is replaced with a compensated data word derived from one interpolation of a correct preceding and following data word; (b) the plurality of erroneous data words are replaced with respective compensated data words derived from a plurality of interpolations of the correct preceding and following data words; and (c) at least the first of the predetermined number of successive erroneous data words is replaced with the preceding correct data word. </p> |
