Claims

[Claims for Utility Model Registration] A pulse width expansion circuit that is given transmission data that is a serial binary signal and expands the pulse width of the transmission data to a time width that is at least twice as long as a 1-bit time slot. A flip-flop circuit is given transmission data as a value signal and divides it, an output signal of the pulse width expansion circuit and two output signals of mutually opposite phases of the flip Φ-flop circuit are given, and the pulse width is A driver that generates a bipolar signal whose polarity changes according to the alternation of the logical values of the two output signals of the flip-flop circuit for a period i during which the output signal of the expansion circuit is "1", and transmits the output signal of this driver to the receiving side. A transmission line that sets the polarity level of each bipolar signal applied through this transmission line to a respective threshold.
In a pulse transmission device comprising a receiver that determines each logical value by comparing it with a level, and a waveform shaping circuit that shapes and outputs the output signal of this receiver, the pulse width expansion circuit is provided at a stage before or after the pulse width expansion circuit. a delay circuit connected to the receiver, from the time when the bipolar signal starts changing from "1" of one polarity to "1" of the other polarity to the time point when it crosses the threshold level of the other polarity; The delay time until the same signal is “0”
'' to either polarity's ``1'', a delay circuit having a delay time equal to the difference between the change start point and the time when the polarity crosses the threshold level is provided. pulse transmission device.
