Abstract
Abstract A system for selectively storing parallel trains of digital information produced in a converter from a plurality of received signals, comprises a plurality of stores arranged in parallel storing channels, a plurality of comparators connected between a pair of stores and between corresponding outputs of the converter to ascertain coincidence between received and stored information, counting circuits for registering each match in respective comparators, and preference logic circuits for resetting all stores except the ones at which a match occurs.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
173 words
A digital data handling system for use in connection with receiver means adapted for receiving signals from a plurality of transmitters, comprising: means for converting the received signals into parallel output trains of binary digital information representing predetermined parameters of each signal, a plurality of groups of storing units arranged in parallel storing channels connected to respective outputs of said converting means, a plurality of comparing means each assigned to at least one pair of storing units in each group for producing an output signal when the stored digital information in each unit of said pair corresponds to information at corresponding outputs of said converting means, a plurality of counting means assigned to each comparing means and controlled by the output signal therefrom, and a plurality of preference logic circuits each assigned to a pair of storing units for producing a reset signal for said pair when a coincidence of output signals from a corresponding comparing means, from a corresponding counting means and from any of the subsequent and preceeding comparing means, occurs.
Claim 2
