Abstract
A circuit module for data processing comprises several first inputs (I.sub.x,i), several second inputs (I.sub.y,i) and several outputs (I.sub.i,j). First transistors (T.sub.i,j) combine the first and second inputs. Each of the first transistors (T.sub.i,j) is connected at its emitter or source with a first input and at its base or gate with a second input. Each second input is further connected to the base or gate and the emittor or source of a second transistor (T.sub.i). The currents of the outputs correspond to the product of the currents through the individual inputs. By combining the outputs sum products can be calculated, especially for computing discrete probability distributions. The combination of several circuit modules allows to solve complex signal processing tasks.
