Abstract
Abstract THE NONLINEAR CHARACTERISTIC OF THE DECODER IS APPROXIMATED BY A PLURALITY OF DIFFERENTLY SLOPED STRAIGHT LINE SEGMENTS AND EACH TERNARY CONDITION IS REPRESENTED BY A DIFFERENT PAIR OF BINARY DIGITS. A FIRST SIGNAL, PRODUCED BY THE MOST SIGNIFICANT TERTIARY DIGITS OF A CODE GROUP, INDICATES THE MINIMUM VOLTAGE OF THE SEGMENT CONTAINING THE CODE GROUP. A SECOND SIGNAL, PRODUCED IN RESPONSE TO AT LEAST THE LEAST SIGNIFICANT DIGITS OF THE CODE GROUP, INDICATES THE POSITION OF THE CODE GROUP ALONG SAID SEGMENTS. A WEIGHTING AND SUMMING CIRCUIT RESPONDS TO THESE TWO SIGNALS TO PRODUCE THE DECODER OUTPUT.
