Abstract
An encoding and decoding system for electronic data communication system, wherein each character to be transmitted is encoded as a unique multi-bit binary value. The total number of bits as well as the number of logic one bits in all unique multi-bit binary values are the same. A pulse generating means generates a wide pulse for each logic one and a narrow pulse for each logic zero. The pulses which make up a unique pulse form for each data character to be transmitted are of alternating polarity and are transmitted as analog signals.
