ABSTRACT:
1. In a system for transmitting a quantized signal having a definite maximum value, a reentry circuit comprising a cyclically operating electronic stepper having a cycle length in step-positions corresponding to the number of steps represented by said maximum value, and successively stepping in response to step-signal input thereto, each position of said stepper including means determinative of the generation of a respective one of three-or-more valued signals, and said circuit including means for, in effect, cancelling, once or more, from the output of said circuit a preassigned whole number of said signal steps whenever the output signal value would exceed said maximum value, and means for converting a group of different step-valued signals into a series of step-pulses to step said stepper around from an initial position through the number of steps represented by said series of pulses.
13. In a system for combining and individually weighting indications each in the form of a marking voltage on a conductor, means to translate each marking voltage in succession into a number of pulses determined by the weighting factor assigned to the particular conductor, a register operating in a closed cycle, said register having positions equal in number to the range of values to be indicated, means to cause said pulses to step said register around through one or more of its cycles and to stop in the position determined by the total number of said pulses, an output circuit, and means to produce an output current in said circuit the value of which is different for each different position in which said register stops.
19. In combination, stepping means for generating multivalued signals, pulsing means for driving said stepping means, a plurality of testing points, means for distributing said signals in random manner over said testing points, and means for testing said points for producing a number of pulses determined by the signal indicated and the weighting factors assigned to respective points, said last-mentioned means including means for driving said pulsing means at preassigned interval.
