ABSTRACT:
A filter architecture for high-resolution video applications of the type comprising at least one filter block having a plurality of digital inputs which receive through an interface components of a television signal and some outputs through which to take the result of a filtering operation for noise associated with the television signal also comprises in the filter block at least one interpolator block connected to said inputs and operating with fuzzy logic to execute a television signal scanning conversion to be presented on additional outputs of the filter block.
