A data transmission system including a device that delays a signal having a predetermined base frequency so as to generate a reference-phase signal having a reference phase, a delay signal more delayed than the reference signal by a unit of time, and an advance signal more advanced than the reference signal by the unit of time; a device that selects one of the reference-phase, delay, and advance signals so as to output a data signal in which a phase of one of the rising and falling edges of the data signal varies in accordance with values of transmitted data, and a phase of the other of the edges is constant; a device that generates a reference signal at the timing of one of the rising and falling edges of the data signal, said one having the constant phase; and a device that reproduces the data by measuring a phase difference between the generated reference signal and the data signal at the timing of the other of the rising and falling edges which has the varying phase. |
