PURPOSE:To apply accurate modulation/demodulation of data by sending data of a section disabling modulation caused at the frequency changeover of spread spectrum communication without missing. CONSTITUTION:The 1st buffer amplifier 1 of a transmission section of a data processor samples and holds serial input data id within a prescribed time, the data and the same kind of data within a prescribed time of the (n-1)th time just before are stored in the 1st memory 3 altogether and all the content is read in Baud rates being a and n multiples of the Baud rate of serial input data to replace the read code with a prescribed pattern by a transposition circuit 21, and the data is outputted from the 2nd buffer 5 as serial transmission data in a time being 1/a of the prescribed time. The serial transmission data L from the transmission section is applied with the inverted operation from that of the transmission section at the reception section, and the data is outputted from the 4th buffer 10 as the serial output data in the same Baud rate as that of the serial input data. |
