<p>The device has signal receiving systems (S1, S2) receiving respective input signals (y, -y), where the signal (-y) is equal to opposite of the signal (y). Two sets of processing units deliver respective output signals (X1, X2). A third set of processing units generates two functions such as weighted sum and difference of two output signals. A fourth set of processing units calculates the signal (y), from the weighted sum and difference of the two output signals.</p> |
