A METHOD FOR TRANSMITTING BINARY DIGITAL WAVEFORMS BY CONVERTING SAID WAVEFORMS INTO POLYBINARY DIGITAL WAVEFORMS HAVING B SIGNALLING LEVELS, B BEING AN INTEGER GREATER THAN THREE, WHICH METHOD COMPRISES THE STEPS OF: (A) COMBINING THE PRESENT BINARY PULSE WITH THE BINARY OUTPUT PULSE GENERATED IN THE PREVIOUS (B-2) COMBINATIONS OF THIS STEP (A), AND PROVIDING A BINARY OUTPUT PULSE OF ONE POLARITY IF THE NUMBER OF BINARY ONES IN SAID COMBINATION IS EVEN, AND OF THE OPPOSITE POLARITY IF THE NUMBER OF BINARY ONES IS ODD; AND (B) ADDING (B-1) SUCCESSIVE BINARY OUTPUT PULSES FROM STEP (A) TO OBTAIN A POLYBINARY OUTPUT SIGNAL; (C) TRANSMITTING SAID POLYBINARY WACEFORM THROUGH A TRANSMISSION MEDIUM TO A RECEIVER; (D) AT SAID RECEIVER, SENSING THE LEVEL OF SAID POLYBINARY SIGNAL DURING EACH PULSE INTERVAL TO ASCERTAIN WHETHER THAT LEVEL IS ODD-NUMBERED OR EVEN-NUMBERED; (E) INDICATING THE RECEIPT OF A BINARY PULSE OF ONE POLARITY WHEN AN ODD-NUMBERED LEVEL IS SENSED; AND (F) INDICATING THE RECEIPT OF A BINARY PULSE OF THE OPPOSITE POLARITY WHEN AN EVEN-NUMBERED LEVEL IS SENSED.
