Abstract
A filter comprising a charge-coupled device having a first group of cells weighted according to a recurring filter law and having a second group of cells weighted according to a non recurring filter law. The cells of the first and second groups are interposed alternately and the displacement of the charges under these cells is carried at frequency twice that of the sampling rate of the input signal. Thus the effects of transfer inefficiency are suppressed without added hardware.
