Telemetering decoder system

Claim 1

IN A TELEMETERING DECODER SYSTEM FOR DECODING A PULSE TRAIN COMPOSED OF REPETITIVE FRAMES OF TIME-MULTIPLEXED SIGNAL CHANNELS WHERE ONE SIGNAL CHANNEL OF EACH FRAME CONTAINS AN INDICATION OF A FULL-SCALE SIGNAL VALUE, ANOTHER CHANNEL OF EACH FRAME CONTAINS AN INDICATION OF A ZERO-SCALE SIGNAL VALUE AND AT LEAST ONE SIGNAL CHANNEL OF EACH FRAME CONTAINS A FRAME SYNCHRONIZING PULSE PATTERN, THE COMBINATION COMPRISING: CIRCUIT MEANS FOR SUPPLYING THE PULSE TRAIN; A CLOCK-PULSE GENERATOR FOR GENERATING CLOCK PULSES AT A RATE WHICH IS A PREDETERMINED NUMBER OF TIMES GREATER THAN THE PULSE TRAIN CHANNEL RATE; FREQUENCY SYNCHRONIZER CIRCUIT MEANS RESPONSIVE TO BOTH THE PULSE TRAIN AND THE GENERATED CLOCK PULSES FOR CONTROLLING THE CLOCK-PULSE GENERATOR TO MAINTAIN THE DESIRED RELATIONSHIP BETWEEN THE CLOCK RATE AND THE CHANNEL RATE; A FIRST PLURAL-STAGE BINARY COUNTER FOR COUNTING THE GENERATED CLOCK PULSES; PHASE SYNCHRONIZER CIRCUIT MEANS RESPONSIVE TO THE PULSE TRAIN FOR SYNCHRONIZING THE RECYCLING OF THE FIRST BINARY COUNTER WITH THE OCCURRENCE OF THE PULSE TRAIN CHANNEL INTERVALS; CIRCUIT MEANS COUPLED TO THE FIRST BINARY COUNTER FOR DEVELOPING SEPARATE SETS OF CHANNEL-RATE TIMING PULSES CORRESPONDING TO DIFFERENT POSITIONS WITHIN THE CHANNEL INTERVALS; A SECOND PLURALSTAGE BINARY COUNTER FOR COUNTING ONE SET OF CHANNELRATE TIMING PULSES; FRAME SYNCHRONIZER CIRCUIT MEANS RESPONSIVE TO THE PULSE TRAIN FOR SYNCHROZIZING THE RECYCLING OF THE SECOND BINARY COUNTER WITH THE OCCURRENCE OF THE FRAME SYNCHRONIZING PULSE PATTERNS IN THE PULSE TRAIN; CIRCUIT MEANS COUPLED TO THE SECOND BINARY COUNTER FOR DEVELOPING SEPARATE SETS OF FRAME-RATE GATING PULSES CORRESPONDING TO DIFFERENT CHANNELS WITHIN THE FRAME INTERVALS; CIRCUIT MEANS FOR GENERATING COUNTING PULSES AT A HIGHER RATE THAN THE PULSE TRAIN CHANNEL RATE AND RESPONSIVE TO THE PULSE VALUE OF THE PULLSE TRAIN DURING EACH CHANNEL INTERVAL FOR GENERATING A PULSE GROUP HAVING A NUMBER OF PULSES REPRESENTATIVE OF SUCH PULSE VALUE; COUNTING CIRCUIT MEANS RESPONSIVE TO THE PULSE GROUP GENERATED FOR EACH CHANNEL INTERVAL FOR DEVELOPING A PLURALBIT PULSE CODE SIGNAL REPRESENTATIVE OF THE PULSE VALUE FOR THE CHANNEL INTERVAL; CIRCUIT MEANS CONTROLLED BY AT LEAST ONE OF THE CHANNEL-RATE TIMING PULSES AND THE FRAME-RATE GATING PULSES FOR THE FULL-SCALE CHANNELS AND RESPONSIVE TO THE FULL-SCALE PULSE CODE SIGNALS FOR ADJUSTING THE RATE OF GENERATION OF THE COUNTING PULSE IF SUCH SIGNALS DEPART FROM A DESIRED PREDETERMINED FULL-SCALE VALUE; CIRCUIT MEANS CONTROLLED BY AT LEAST ONE OF THE CHANNEL-RATE TIMING PULSES AND THE FRAME-RATE GATING PULSES FOR THE ZERO-SCALE CHANNELS AND RESPONSIVE TO THE ZERO-SCALE PULSE CODE SIGNALS FOR ADJUSTING THE INITIAL COUNT CONDITION OF THE COUNTING CIRCUIT MEANS IF SUCH SIGNALS DEPART FROM A DESIRED PREDETERMINED ZERO-SCALE VALUE; A PLURALITY OF SEPARATE OUTPUT SIGNAL CHANNELS; A PLURALITY OF INDIVIDUAL SIGNAL TRANSFER CIRCUIT MEANS, EACH TRANSFER CIRCUIT MEANS COUPLING ONE OF THE OUTPUT CHANNELS TO THE COUNTING CIRCUIT MEANS; AND MEANS FOR SUPPLYING THE FRAME-RATE GATING PULSES FOR THE DIFFERENT CHANNELS TO DIFFERENT ONES OF THE SIGNAL TRANSFER CIRCUIT MEANS FOR ENABLING THESE CIRCUIT MEANS TO TRANSFER THE PULSE CODE SIGNALS FOR THE CORRESPONDING CHANNELS TO THEIR RESPECTIVE ONES OF THE OUTPUT SIGNAL CHANNELS.
