Abstract:
    The field of the invention is that of electronic or electro-optical multiplexers for the transmission of digital data at high speed. The device according to the invention makes it possible to multiplex two NRZ-type, binary-coded signals. It mainly comprises: A generator of four primary signals; Means of electronically selecting said primary signals controlled by the two initial signals for generating the final multiplexed signal. The selection means are complemented with a logic block for generating four logic signals, all different, dependent on the two initial signals. The main advantage of this device is to allow for the use of so-called ETDM technologies for the transmission of high-speed multiplexed signals inasmuch as the necessary logic circuits operate mainly at a frequency half that of the multiplexed signal. These electronic transmission technologies are less expensive than the so-called OTDM optical technologies.
