<p>A circuit is disclosed for deriving an output which is indicative of the centre of gravity of electric signals representative of fuzzy information distributed over a plurality of lines. In one embodiment the circuit comprises a weighted summing circuit which forms a sum from the signals after multiplying each signal by a respective value corresponding to the grade of its said line, and a simple summing integration circuit which executes summing integration of the electric signals without any weighting. In an alternative embodiment the circuit comprises a weight summing integration circuit which executes summing integration of the signals after multiplying each such signal by a respective value corresponding to the grade of its line, and a simple summing circuit that simply sums the signals without weighting. In both embodiments a comparator then makes a comparison between the outputs of the two circuits. <IMAGE></p> |
