Method and device for processing signals

To process signals, particularly video signals, the input signal is convoluted with the pulse response of one line, on the one hand, and, on the other hand, delayed by the period of one line, for the purpose of two-dimensional filtering. During the convolution, the signal is in each case delayed by the period of one pixel for each coefficient of the pulse response, multiplied by the relevant coefficient of the pulse response and the result is added together. This process is repeated for each line of the pulse response and all convolution results are added together. The result of the addition corresponds to the signal of an image which was convoluted with a two-dimensional arbitrarily real dot image.
