Abstract

PURPOSE:To output an input data as converted to a symmetrical waveform suitably with a simple constitution, by providing a D flip-flop which takes an NOR output between the output of a shift register and the output of a basic oscillator as a reset input. CONSTITUTION:An output (a) of a basic oscillator 1 is inputted to a clock terminal CL of a D FF3 and to one terminal of a NOR gate 4. A data (c) to be transmitted is sequentially inputted to another terminal of the NOR gate 4 from a shift register 2. Further, the output of the NOR gate 4 is inputted to a reset terminal R of the D FF3, and a Q output (b) of the D FF3 is inputted to a clock terminal CL of the shift register 2 and also inputted to a terminal D of the D FF3 via an inverter 5. The signal (b) of this Q output terminal is outputted as a symmetrical wave signal from an output terminal 6.
