ABSTRACT:
The device is associated with a logic apparatus thereto four lines are coupled for transmitting logic data having a predetermined frequency and supplying at the output thereof a multiplexed signal having a frequency which is four times the mentioned frequency and responsive to the control of the subject device which comprises a binary digit pseudo-random sequence source and four Exclusive-OR logic circuits coupling said source to said apparatus in such a way as to define for said multiplexed signal a pseudo-random sequence having a period 2.sup.7 -1, as the tributary data is T1=T2=T3=T4=".0.".
