ABSTRACT:
In a digital data transmission system, a transmitting device converts the data to be transmitted into a series of bits, in the form of data pulses. Each data pulse is positioned between successive synchronous pulses having a fixed time period, and each bit is represented by the time length between a data pulse and a preceding synchronous pulse or a succeeding synchronous pulse. The transmitting device transmits the series of the data pulses and the synchronous pulses. A receiving device receives the series of the data pulses and the synchronous pulses and decodes the same to read the data.
