Claim One:
1. A decision device for making probabilistic decisions regarding the most recent set, W, of a series of binary 1 and 0 sample signals comprising, in combination: terminal means for connection to separate sources of binary 1 and 0 sample signals; W-counting means for counting the total number of 1 and 0 sample signals received and providing an output signal when the total exceeds a preselected number, W; T-counting means for receiving a continuing series of binary 1 and 0 signals and converting them to a number of output signals, T.sub.i, where i is a number from 1 to a preselected value A, T.sub.A corresponding to a probability value of 1's relative to the number of 1's and 0's in said T-counting means which has been selected as the probability level at which an Accept decision will be made; probability-setting means, connected to said terminal means, said W-counting means and said T-counting means, said probability-setting means including special-purpose, pseudorandom, binary-sequence-generator means, for causing the count of said T-counting means, after the W-counting means has reached a count of W, to be reduced by one unit with a probability of T.sub.i /W if the received input binary sample is a 0, and to be increased by one unit with a probability of W-T.sub.i /W if the received input binary sample is a 1; M-counting means, connected to said terminal means, for counting said 1 and 0 samples and producing an output signal when the total number of 1's and 0's becomes equal to M, a preselected binary number related to the maximum number of samples to be considered before a NON-Accept decision is made, M being a number greater than the number W; logic means, connected to receive the output signal of said M-counting means and the T.sub.A output signal of said T-counting means, for generating a Non-Accept output signal whenever said M-counting means reaches a count of M before said T-counting means reaches a count of T.sub.A and for generating an Accept signal whenever said T-counting means reaches a count of T.sub.A before said M-counting means reaches a count of M.
