    Abstract: The device transforms an analog input signal with N components x(0), x(1) . . . x(N−1) into an output signal with N components X(0), X(1) . . . X(N−1) functions of said components x(0), x(1) . . . x(N−1), said device comprising basic addition and/or subtraction cells linked in a butterfly-type architecture to perform said functions, each basic cell comprising an operator performing a conditional division by two of the result of the addition operation or subtraction operation performed, the condition being the saturation of said operator.
