Abstract
1380925 Electric analogue calculating QELEQ Ltd 10 March 1972 [18 March 1971] 7247/71 Heading G4G An analogue data handling apparatus receives as an input a set of values representing different variables, this set is compared with another set of values representing the same variables and which are known and stored in the apparatus and an output signal is derived which is indicative of the degree of correspondence between the two sets. In Fig. 2, an interface circuit 1, a difference circuit 3, a modulus circuit 6, a comparator 8 and a multiplier 11 are provided for each variable and the output of this chain is a signal inversely proportional to the deviation of the value of the variable in the input set from its value in the stored set in store 34 multiplied by a weighting factor in accordance with the significance of the variable in the set. These outputs for all the variables are summed at 14 and passed through a logarithmic stage 16 to give the output indicative of the degree of correspondence. The inputs can be sequentally compared with a plurality of stored sets.
