ABSTRACT:
The invention relates to hybrid filters comprising a recursive part and a non-recursive part which make it possible to synthesize the filter by splitting the desired pass-band into two. It consists in using for the design of such a filter a charge-coupled device (CCD) in which these two parts are directly linked by a simple charge transfer mechanism without any other connection.
