Error Detection And Correction For Adaptive Memories

The arrangement reduces reject rates in a one out of n recognition network.

A plurality of n threshold circuits TU have inputs connected to input matrix IM for the purpose of providing a one out of n recognition system. The outputs from these threshold circuits are normally utilized to indicate the value of the character scanned or recognized. Where it is known that ambiguities exist between characters, such as, e. g., between 3 and 5, the outputs from the TU's which recognize the 3 and the 5 are supplied to And 7 along with timing signal TS.

If an ambiguity exists, which causes a reject, both outputs are Present and a timing pulse then causes And 7 to supply an output. This is returned under the control of a recycle control 9 via selected reset lines 11 to predetermined positions in IM. These reset signals cause IM to supply a subset of inputs arranged to eliminate ambiguities that exist in the previous information. The system is then recycled and TU circuitry again determines whether or not they can distinguish between the characters.
